We know that the 80% H₂SO₄ solution has a density of 1.80 g/mL. The mass percentage means that in 100 g of solution, there are 80 g of H₂SO₄. To find the mass of the solution needed to get 19.6 g of H₂SO₄, we can set up a proportion: ...
Given Mass of solute (K(2)CO(3))=2.5g Volume of solution =1000ml Density of solution =0.85g ml^(-1) Asked Molality of solution (m)=? Formulae: m=(W(B))/(M(B))xx(1000)/(W(A)) Explanation: m= molality of solution, M(B)= Molecular weight solute
An osmolarity is a unit of measurement that measures the osmotic concentration. It shows the number of osmoles per liter of the solution. An osmole is a unit of measurement that measures the number of moles of the solute that contributes to the osmosis pressure of the solution. ...

Calculate the molality of 2.0 M MgCl2 solution. The density of the solution is 1.127 g/mL. (The molar mass of MgCl2 = 95.211 g/mol, and the molar mass of H2O is 18.02 g/mol.) a) 1.77 m b) 2.14 m c) 2.25 m d) 1.51 m e) 2.00 m ...
How do you determine the mass of a solute if you are given the molality of a solution and the volume of water in the solution? If you dissolved 10.0 grams of salt in 100.mL of water (assume the density of water is 1 g/mL), what would b...
Calculate the molality of a 4.17 M aqueous NaCl solution. (density = 1.08 g/mL) Determine the amounts of solute and solvent needed to prepare the following solutions. 1. 2.0 M aqueous NaCl solution. 2. 1.0 m aqueous KCl solution. 3. 25% by mass a...
Molalityis used to express the concentration of a solution when you are performing experiments that involve temperature changes or are working with colligative properties. Note that with aqueous solutions at room temperature, the density of water is approximately 1 kg/L, so M and m are nearly the...
Step 1: Calculate the molality of the NaCl molality (m) of NaCl = moles of NaCl/kg water From theperiodic table, find the atomic masses of the elements: atomic massNa = 22.99 atomic mass Cl = 35.45 moles of NaCl = 31.65 g x 1 mol/(22.99 + 35.45) ...
