Aclosed container has 4.02 β
1023 atoms of a gas. each atom of the gas weighs 1.67 β
10β24 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 β
1.67) β
(1023 β
10β24) = 6.7134
5.69 grams, because (4.02 + 1.67) β
(1023 β
10β24) = 5.69
0.67 grams, because (4.02 β
1.67) β
(1023 β
10β24) = 6.7134 β
10β1
0.57 grams, because (4.02 + 1.67) β
(1023 β
10β24) = 5.69 β
10β1
