Answer to Question #209216 in General Chemistry for ling

Question

Which of the following systems will have the greatest volume at STP?

a. 1.00 g N 2 (MM = 28 g/mol)

b. 1.00 g NH 3 (MM = 17 g/mol)

c. 1.00 g He (MM = 4 g/mol)

d. 1.00 g CO 2 (MM = 44 g/mol)

Answer 1

Volume = 22.4/4 = 5.6

So

C)1.00 g He (MM=4g/mol)

will have greatest volume at STP
