The salinityof a solution is defined as the grams of totalsalts per kilogram of solution. An agricultural chemist uses a so-lution whose salinity is 35.0 g/kg to test the effect of irrigatingfarmland with high-salinity river water. The two solutes are NaCl and MgSO₄, and there are twice as many moles of NaCl asMgSO₄. What masses of NaCl and MgSO₄ are contained in 1.00 kg of the solution?
