Answer:
31.95 g
Explanation:
find the molar mass of Al(NO3)3
(Al = 27, N = 14, O = 16)
molar mass of Al(NO3)3 = 27+ (14+16×3)×3
= 213 gmol^-
mass = 213 ×0.15
= 31.95g
The answer is four. The law of conservation of mass basically says that whatever is but in will always have the same mass coming out. so for example if you had 10 grams of water and then you heated it up, it is still 10 grams of water.
Answer:
16kg/s
Explanation:
The formula for acceleration is [ a = f/m ] where f = force and m = mass
a = 4/0.25
a = 16
Best of Luck!
