A closed container has 4.02 ⋅ 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?
6.71 grams, because (4.02 ⋅ 1.67) ⋅ (1023 ⋅ 10–24) = 6.7134
5.69 grams, because (4.02 + 1.67) ⋅ (1023 ⋅ 10–24) = 5.69
0.67 grams, because (4.02 • 1.67) ⋅ (1023 ⋅ 10–24) = 6.7134 • 10–1
0.57 grams, because (4.02 + 1.67) ⋅ (1023 ⋅ 10–24) = 5.69 ⋅ 10–1

Best ResponseYou've already chosen the best response.1we have to compute this: \[\Large \left( {4.02 \cdot {{10}^{23}}} \right) \cdot \left( {1.67 \cdot {{10}^{  24}}} \right) = ...?\]

Best ResponseYou've already chosen the best response.1you have to multiply, here are your steps: \[\large \left( {4.02 \cdot {{10}^{23}}} \right) \cdot \left( {1.67 \cdot {{10}^{  24}}} \right)= \left( {4.02 \cdot 1.67} \right) \cdot {10^{23  24}} = ...?\]
