How many grams of NaCl do you need to make 150ml of a 0.8M stock solution?

Molarity (M) = mol / liter
= moles/ 1000ml
Therefore, 0.8M = 0.8 mol/ 1000 ml
Know that the units cancel out to mol:
(0.8 mol/1000 ml)*(150ml) = ? mol
if you multipy ? mol by the molar mass of NaCl , you would end up with grams of NaCl
(? mol)*(__ g/ mol)= ___g NaCl
= moles/ 1000ml
Therefore, 0.8M = 0.8 mol/ 1000 ml
