4. 4 sacks of corn kernels are shown below.-what is their Average mass?-What is the total mass of corn kernels ?
4 kernels = 15kg, 6kg, 10kg, 5kg
total mass of corn kernels
= 15+6+10+5
= 36kg
Average = total data/frequency
= (15+6+10+5)/4
= 36/4
= 9 kg
So, the average mass is 9kgand the total mass is 36kg

6. what is the molarity of H2SO4 if the molecular mass is 98,S.G 1.84 and purity is 97%?Tolong Saya,Thank you.
Mr = 98
% = 97
massa jenis 1,84
Molaritas =( % x 10 x massa jenis) /Mr
M = 97x10x1,84/98 = 18,2 molar
7. the ratio of amy's mass to bala's mass is 4 : 3. the ratio of bala's mass to chandra's mass is 9 : 7. what is the ratio of amy's mass to bala's mass to chandra:s mass?
A : B
4 : 3
B : C
9 : 7
A : B : C
= (4x9) : (3x9) : (7x3)
= 36 : 27 : 21
= 12 : 9 : 7
Jadi perbandingannya adalah 12 : 9 : 7

10. a kitten and a basket has a mass of 3 kg . A hamster and a similar basket has a mass of 1.4kg . the mass of the kitten is 5 times the mass of the hamster .a. what is the mass of the hamster ? , b. what is the mass of the kitten ?
kitten = x ,hamster = y and baskest = z
x+z = 3 kg
y+z = 1,4 kg
z = x- y = 3 kg - 1,4 kg = 1,6 kg
x+y = 4,4 kg - 1,6 kg = 2, 8 kg
x = 5y
5y +y = 2,8 kg
6y = 2,8 kg
y = 2,8 kg /6
y = 0,47 kg
x = 5y
= 5 * 0,47 kg
= 2,35 kg
a. mass off hamster = 0,47 kg
b. mas off kitten = 2,35 kg
bonus...mass of basket = 1,6 kg
thank's
11. The mean mass of 18 bags of oranges is 2.5 kg. if a 19th bag containing 4 kg of oranges is included, what would the new mean mass of the 19 bags be?
Mean is the total mass divided by the number of bags. So to find the new mean, we need the new total mass and, to find the new total mass, of course we need the old total mass.
Here I define some symbol I will use.
T1 : old total mass
M1: old mean
N1: old number of bag
T2: new total mass
M2: new mean
N2: new number of bag
A: additional mass
Find the old total mass
T1 = N1 x M1 = 18 x 2.5 = 45
And the add the old total mass with the additional one to find the new total mass
T2 = T1 + A = 45 + 4 = 49
The we find the new mean by deviding it with the number of bags
M2 = T2/N2 = 49/19 = 2.58
So the new mean mass is 2.58 kg.
Hope this would be helpful for you.

15. A kitten and a basket has a mass of 3 kg. A hanster and a similar basket has a mass of 1.4 kg. The mass of the kitten is 5 times the mass of the hamster. (a) what is the mass of the hamster? (b) what is the mass of the kitten?
hamster = x
kitten =y
basket=z
y=5x
x + z = 1,4
y+ z = 3. (+)
x-y = -1,6
x-5x=-1,6
6x = 1,6. x =0,267
y = 5x=5×0,267=1,335

Then pressure per cm
35,000 / 70 = 500 g / cm
Or
0,5 kg / cm
