Question

How many grams of sodium chloride are present in a 0.75 M solution with a volume of 500.0 milliliters?

Answer 1

M = mol/l

So, M = 0.75 M
       V = 500.0 ML
        Mols = X
c = n/v
n = c(v)
n = 0.75(0.5)
   = 0.375mol
sodium Chloride is 58.5g/mol
1mol = 58.5g, 0.375mol(g)
0.375mol(58.5g)/1mol
Your answer would be: 21.94g




Hope that helps!!!
