C. mass X to liters Y
D. mass X to moles Y to liters Y
( Please Help )

Answer 1

A. mass X to moles X to moles Y to liters Y

Step-by-step explanation:

Remember: moles are the great converter. They're basically just a made-up concept meant to facilitate conversions!

Starting with mass X, you must then convert to moles X.

Once you have moles X, convert moles Y. Think of a chemical equation: the mole ratios are the coefficients!

Once you have moles Y, all you have to do is convert to liters Y. You can do this with the molarity equation M = mol/L, or if it's a gas at STP you know the conversion!
