  10. Problems to Know… • You dissolve 10.0 g of NaCl in 150.0 mL of solution. Determine the concentration in molarity. • [1.14M NaCl] • Describe how to make 250.0 mL of 0.100M NaOH from a stock solution of 8.00M NaOH. • [Take 3.125 mL of 8.00M NaOH and add enough water to make 250.0 mL of solution.]
