A solid mixture contains MgCl2 (molar mass = 95.218 g/mol) and NaCl (molar mass = 58.443 g/mol). When 0.5000 g of this solid is dissolved in enough water to form 1.000 L of solution, the osmotic pressure at 25.0 oC is observed to be 0.3950 atm. What is the mass percent of MgCl2 in the solid? (Assume ideal behavior for the solution.)

A solid mixture contains MgCl2 (molar mass = 95.218 g/mol) and NaCl (molar mass = 58.443 g/mol). When 0.5000 g of this solid is dissolved in enough water to form 1.000 L of solution, the osmotic pressure at 25.0 oC is observed to be 0.3950 atm. What is the mass percent of MgCl2 in the solid? (Assume ideal behavior for the solution.)

A solid mixture contains MgCl₂ (molar mass 95.218 g/mol) and NaCl
(molar mass = 58.443 g/mol). When 0.5000 g of this solid is dissolved in enough
water to form 1.000 L of solution, the osmotic pressure at 25.0 °C is observed to be
0.3950 atm. What is the mass percent of MgCl₂ in the solid? (Assume ideal
behavior for the solution.)
