Calculate The Molality Of The Following Aqueous Solutions
Calculate The Molality Of The Following Aqueous Solutions. (a) 2.50 m nacl solution (density of solution = 1.08 g/ml), (b) 48.2 percent by mass kbr solution. B) 45.2 percent by mass kbr.
Calculate the molarity of each aqueous solution with from www.chegg.com
An aqueous solution of hcl contains 25% hci by mass. Molality = moles of solute / kg of solvent. So to find the granted anything, i would have a multiply and moves by the molar mass.
Density Of Solution=3.107 Gm/ Ml.
1.329 g/cm3 times 1000 cm3 = 1329 g (the mass of the entire solution) 1329 g minus 571.4 g = 757.6 g = 0.7576 kg (the mass of water in the solution) 571.4 g / 98.0768 g/mol = 5.826 mol of h2so4. Since the molar mass (gram formula mass of sodium chloride is 58 grams per mole ( na = 23 g and cl = 35 g , 23 + 35 = 58 g/mol) the mole value of the nacl is 0.5 moles (29 g / 58 g/mol = 0.5 moles). Molality = 0.5 moles / 1.0 kg = 0.5 molal.
So Give Us The Similarity.
