Question

What is the volume of .80 g of O2 gas at STP?

Answer 1

Answer:0.56L

Explanation:Molar mass of O2=32

N=0.8/32

N=0.025
V=0.025 x 22.4=0.56L

Answer 2

To find the number of grams 0.80 g of O2 has you must take the number of grams and divide it by the molar mass. The molar mass of O2 is 32.00.

0.80/32.00=0.025 mol

Now to convert this to liters at STP, you have to multiply that, by 22.4.

0.025*22.4=0.56 L
