= 17 210/270
= 17 21/27
= 17 7/9 gallons
7. how many moles of water is 5.87 x 10 22 molecules ?
Saya jawabnya pakai bahasa indonesia ya :p
Diketahui : Jumlah partikel : 5.87 x [tex]10^{22}[/tex]
Jumlah partikel = mol x L (bilangan avogadro)
5.87 x [tex]10^{22}[/tex] = mol x 6.02 x [tex]10^{23}[/tex]
mol = 0.097 mol

9. 1. A cubical bath has a side length of 90 cm. If the tub is filled with water, how many liters of water are in the tub?
Jawab:
729 liters
Penjelasan dengan langkah-langkah:
To find out how many liters of water are in the tub, we need to find the volume of the tub and then convert it to liters. Since the bathtub is a cube, the volume can be found by using the formula:
Volume = side length^3
In this case, the side length is 90 cm, so the volume is:
Volume = 90^3 cm^3
To convert cubic centimeters to liters, we divide the volume by 1000. So:
Volume = 90^3 cm^3 / 1000
= 729000 cm^3 / 1000
= 729 L
So the tub is filled with 729 liters of water.
Jawab:
Penjelasan dengan langkah-langkah:
To determine the number of liters of water in the tub, you need to calculate the volume of the tub and then convert it to liters.
The volume of a cube can be calculated by using the formula: V = s^3, where s is the length of one side of the cube.
So, for a cubical bath with a side length of 90cm, the volume of the tub is:
V = 90^3 cm^3
V = 729,000 cm^3
1 liter is equivalent to 1000 cm^3
So, to convert the volume of the tub to liters, you can divide the volume in cm^3 by 1000:
V(in liters) = 729,000 cm^3 / 1000
V(in liters) = 729 liters
Therefore, the tub contains 729 liters of water if it's filled.
10. A water flask contained 1 l of water. Peter poured out 1/4 l of water to drink. Mrs Tay added 4/5 l of water into the flask.How much water was in the flask in the end?
Jawaban:
There is 1 11/20 l in the flask in the end.
Penjelasan dengan langkah-langkah:
= 1 l - 1/4 l + 4/5 l
= 20/20 l - 5/20 l + 16/20 l
= 31/20 l (improper fraction)
= 1 11/20 l (mixed number)
11. how many kind of water cycle do you know?
Precipitation : described as any water that falls from the sky in the form of rain, sleet, snow or hail
Evaporation : where water leaves the earth and rises as vapor. Factors that cause evaporation in lakes, streams and the oceans include wind, sun, and solar energy.
Condensation : where vapour is converted back into a liquid. This occurs when wet air moves further into the atmosphere, where it is cooler; and it turns into water, which is where it turns back into precipitation.
12. An alloy of silver and gold weight 15 ounces in air and 14 ounces in water. Assumming that silver loses 1/10 of its weight in water and that gold loses 1/19 of its weight, how many ounces of each metal are in the alloy?
Jawab:
the weight of each metal is
gold = 10 ⁵ / ₉ounce
silver = 4 ⁴ / ₉ ounce
Penjelasan soal:
Soal tersebut menjelaskan bahwa
Terdapat campuran emas dan logamJika di udara 15 ons di air 14 onsJika di air emas kehilangan ¹/₁₉ beratnya dan perak kehilangan ¹/₁₀ beratnyaPembahasan soal:
karena berat asli campuran logam tersebut adalah 15 ons, maka dapat ditulis dengan
[tex]\boxed {emas \ + \ perak \ = \ 15 \ ons}[/tex]
Lalu saya misalkan,
emas = a
perak = b
[tex]\boxed { a+b = 15 }[/tex]
di sini saya akan menggunakan metode eliminasi
a+b = 15
lalu kita masukkan persamaan tersebut menjadi
[tex]\frac{19-1}{19} a + \frac{10-1}{10} = 14\\\\\ \frac{18}{19}a + \frac{9}{10}b = 14 ---> (\times 190) \\\\\frac{18 \times 190}{19} a + \frac{9 \times 190}{10} b = 14 \times 190\\\\\ 180a+171b = 2660[/tex]
lalu kita samakan vaiabel a agar dapat di eliminasi
a+b = 15 ---> ( ×180)
180a + 180b = 2700
Maka,
180a + 180b = 2700
180a + 171b = 2660
_________________ -
9b = 40
b = 40/9
b = 4 ⁴/₉ ons
a = 15 - 4 ⁴/₉
a = 10 ⁵/₉ gram

13. How many grams are in 1.2 x 10²⁴ molecules of water?
Answer
Mass of water = 36 grams
ExplanationMolecules of water is written in formula : H₂O,
to calculate the mass of the water, we should know about realtive molecular mass of water from periodic table :
Mr H₂O = 2 x Ar H + Ar O = 2 x 1 + 16 = 18 g/mole
From Avogadro number ==>
[tex]\boxed{mole\ of\ water\ = \frac{Molecules\ number\ of \ Water}{6,02\ .\ 10^{23} } }[/tex]
mole of water = 1.2 x 10²⁴ /(6.02 x 10²³) = 1.99 mole = 2 mole
Mass of water = mole of water x Mr water = 2 mole x 18 g/mole
= 36 grams of water

19. A house painting company has 8 1/4 gallons of paint available to paint available to paint a house. the paint will be divided equally among 3 painters. how many gallons of paint will each painter receive?.....
I think so..
8 1/4 : 3
= 33/4 :3
= 2.75 atau 2 3/4
so, Many gallons of paint will each painter receive is 2 3/4 ..
8 * 1/4 = 8/4 = 2 gallons There are 3 painters so each painter will get 1/3*2 gallons = 2/3 of a gallon per painter... So, 2/3 of gallon per painter... Thank you :D
