Question

FAN AND MEDAL

Answer 1

A closed container has 2.04 ⋅ 1023 atoms of a gas. Each atom of the gas weighs 1.67 ⋅ 10−24 grams. Which of the following shows and explains the approximate total mass, in grams, of all the atoms of the gas in the container?

0.34 grams, because (2.04 ⋅ 1.67) ⋅ (1023 ⋅ 10−24) = 3.4068 ⋅ 10−1
0.37 grams, because (2.04 + 1.67) ⋅ (1023 ⋅ 10−24) = 3.71 ⋅ 10−1
3.41 grams, because (2.04 ⋅ 1.67) ⋅ (1023 ⋅ 10−24) = 3.4068
3.71 grams, because (2.04 + 1.67) ⋅ (1023 ⋅ 10−24) = 3.71

Answer 5

@iwillpraise you can not put ur question on someone else problem

Answer 6

ok

Answer 7

@kiamousekia
1 mole of H weights 1.008 g
1 mole = 6.02 x 10^23 particles
Mass of 1 atom = 1.008 g / 6.02 x 10^23 = 1.67 x 10^-24 g

Answer 8

okay....

Answer 9

Lol that's real helpful

Answer 10

that was helpful

Answer 11

Soooooo... 2.04x10^23 atoms x 1.67x10^-24 g/atom = 3.41x10^-1 g

Answer 12
