Question

12-7. A mixture of gases containing 1 mole each of He, Ne, and Ar will occupy what volume at STP?

Select one:

a. 22.4 L

b. 44.8 L

c. 67.2 L

Answer 1

Answer #1

At STP 1 mole occupies 22.4 L, In your case, 3 moles of gas ( 1 mole each of He, Ne, and Ar ) will occupy 3 times more volume than 1 mole of gas.

3 moles x [22.4 L/ mole] = 67.2 L

Answer: c. 67.2 L

Hope this helped you!
