A closed container has 5.04 β’ 1023 atoms of a gas. Each atom of the gas weighs 1.67 β’ 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? (1 point)
8.42 grams, because (5.04 β’ 1.67) β’ (1023 β’ 10-24 ) = 8.4168
6.71 grams, because (5.04 + 1.67) β’ (1023 β’ 10-24 ) = 6.71
0.67 grams, because (5.04 + 1.67) β’ (1023 β’ 10-24 ) = 6.71 β’ 10-1
0.84 grams, because (5.04 β’ 1.67) β’ (1023 β’ 10-24 ) = 8.4168 β’ 10-1
