Show how to calculate the molarity of 45 g of hcl in 1.5 L of water
Answered by DrBob222
mols HCl = grams/molar mass
M HCl = mols HCl/L HCl = ?
Answered by ff
so the answer is 45/1.5=30
Answered by DrBob222
No. 45 g is not 45 mols. mols = grams HCl/molar mass HCl as I posted above. THEN, M = mols/1.5 = ?

36.46g/mol/1.5=24.30726Mhcl

45g/36.5g/mol= 1.233mola*1000/1500= 0.822M
