Molar Volume(1mole=24.4L at STP)

Question: Convert 40mL to moles
I converted 40mL to .04L
*Need help in coverting .04L to moles

When you have a situation such as this go back and use dimensional analysis to set up the problem.

0.04L x (1 mol/24.4 L) = ?
You may want to check that number of 24.4 L/mol. It all depends upon what you're calling STP. When I was in school that STP thing was standard. It isn't now.

To convert 0.04L to moles, you need to use the concept of molar volume. The molar volume at STP (standard temperature and pressure) is defined as 1 mole of gas occupying 24.4L of space.

First, determine how many times the molar volume fits into the given volume of 0.04L. Divide 0.04L by 24.4L:

0.04L / 24.4L ≈ 0.00164 moles

Therefore, 0.04L is approximately equal to 0.00164 moles.
