# Show how to calculate the molarity of 45 g of hcl in 1.5 L of water

36.46g/mol/1.5=24.30726Mhcl

## I showed you how to do this. It's two steps.

mols HCl = grams HCl/molar mass HCl

Take that number of mols you calculated and put it into the equation below.

Then M = mols HCl/L H2O.

What's your trouble? All you have to do is to substitute the numbers into the equations I gave you. I won't do it for you but I'll be glad to answer any questions that are confusing you.
