39. At 20°C, a 0.376 M aqueous solution of ammonium chloride has a density of 1.0045 g/mL. Whatis the mass % of ammonium chloride in the solution? The formula weight of NH4Cl is 53.50g/mol.

Calculate the mass percent by volume of 87.6 g of glucose (C₆H₁₂O₆, MM = 180.2 g/mol) in 325 mL of solution.

An aqueous solution of methanol (MM = 32.04 g/mol) has a molality of 1.44 m and a density of 1.15 g/mL. What is the molarity of methanol in the solution?

a 2.65% by mas solution Zncl2 dissolved in water contains 16.0 g of zncl2 calculate the mass of the water in this solution.

What volume (in L) of 3.0 M CaCl2 is needed to make 65 mL solution of 1.2 M CaCl2?

What is the density (g / ml) of a solution of 2525 ml and 1.9 kg?

The density of a solution that is 30.0 % H C l O3 is 1.167 g/mL. Calculate the molarity of the H C l O3 (molar mass is 84.46 g) solution.HINT : % H C l O3 = [mass H C l O3/mass solution] times 100% and Density = 1.167 g solution / 1 mL solution.
