Question

Calculate the number of moles and the number of grams of the following solution 1. 0L of 0. 50M NaCI

Answer 1

Assuming the M is molarity, molarity is equal to mols/volume in liters.

So it would be 50M NaCl = X mols/ 1.0L
50M * 1.0L = X mols
X = 50

50 Mols of NaCl

Now that you have mols, you can then convert mols to grams by doing 50mols NaCl * (58.44 g NaCl/ 1 mol NaCl)
= 2922 grams of NaCl
