1. Ocean water contains 3.5% NaCl by mass. How much salt can be obtained from 254 g of seawater. 2. Calculate the mass of NaCl in a 35-ml sample of 1.3 M NaCl solution. 4.A 122-mL sample of a 1.2 M sucrose solution is diluted to 500.0 mL. What is the molarity of the diluted solution? 5. What is the minimum amount of 6.0 M H2SO4 necessary to produce 15.0 g of Hz(g) according to the reaction? 2Al(s) + 3 H2SO4(aq) ----? Alz(S04)3(aq) + 3 H2(g)
