1. A single mole of AgNo3 weighs 169.88 grams. In order to make a 1M solution, how many grams of AgNo3 would need to be dissolved in 5oomL?
How many moles do you need?
moles = M x L.

• chem -

M = moles/L
So you want 0.5 L and 1 M, you will need 1 x 0.5 = 0.5 mole.
How many grams is that?
moles = g/molar mass
