Convert 42.97 grams of carbon monoxide (CO) to liters at STP.

Question

I don't know how to solve this question

Answer 1

AGAIN, at STP 1 mole = 22.4 liters

1) convert grams to moles:  42.97 g CO x 1 mole CO/28.01 g = 1.5341 moles CO

2) convert moles to liters:  1.5341 moles CO x 22.4 liters/mole = 34.36 liters (4 significant figures)
