Question

You are working with a stock NaCl solution that contains 6.00 g of NaCL for every liter of solution. If you want to make 650.0 mL of solution, how much NaCl will you need?

Answer 1

Using dimensional analysis:

650.0 mL solution x (6.00g NaCl ÷ 1 L solution) x (1 L solution ÷ 1000 mL solution) = 3.90 g NaCl
