Question

Consider two expandable balloons labeled A and B are each filled with different gases. Container A is filled with 20.0 grams of argon, a noble gas, while B contains 0.5 moles of bromine, a diatomic halogen gas. (AW: Ar=40, Br=80)

TRUE OR FALSE WITH EXPLANATION FOR FAVE ANS

1. Both containers have the same mass of gas.
2. At STP, both containers will have the same volume.

Roger the Mole · Accepted Answer

1.
(0.5 mol Br2) x (160 g Br2/mol) = 80 g Br2
So the statement is false.

2.
(20.0 g Ar) / (40 g/mol) = 0.5 mol Ar
So the statement is true.
