How do you calculate the percent by mass of 4.35g of NaCl dissolved in 105 g of water?
% by mass is the mass of the solute divide by the total mass of solution times 100%. Or put another way, % by mass = mass solute/total mass of soln (x100%).Mass solute = 4.35 gMass of solution = 4.35 g + 105 g = 109.35 g (assuming a density of 1g/ml for water)% NaCl by mass = 4.35 g/109.35 g (x100%) = 3.98 % (to 3 significant figures)
What is the molarity of a solution made by dissolving 58.44 g of NaCl in enough water to make 1.0 L of solution?
Divide grams (mass) by molar mass to find moles58.44 (g NaCl/L) / [22.99+35.45](g NaCl/mol NaCl)= 1.000 mol/L NaCl
How is molarity measured?
In moles of substance dissolved in 1 L of water -Apex
If a 25 g sample of sugar was dissolved in 50 g of water The concentration of the solution is?
33% by mass
What is the percent by mass of naHco3 in a solution of 40.0g naHco dissolved in 800.0ml of h2o?
First of all, you need to know the density of the water. The density can be calculated by 1g/ml. Then the mass of H2O can be calculated by DXV=1x800. Then the total mass of the solution is the mass of solvent plus mass of solute. The percentage is 4.76 for this solution.
What is the percent by mass of NaCl in a solution containing 20g of NaCl dissolved in 600g of H2O?
9%
How do you calculate for the mole of a solution?
number of moles is mass divided by molecular mass. the molecular mass of NaCl is 58.44g/mol. therefore you need 58.44g to make one mole
What is the mass percent of NaCl when 6.5g of NaCl dissolves with 250g of water?
This concentration of NaCl is 2,6 g NaCl/100 mL solution.

What is the percent of mass of 4.35 gm of NaCl dissolved in 105.0 gm of water.?
Total mass = 4.35 g + 105.0 g = 109.35 g% by mass of NaCl = 4.35/109.35 (x100%) = 3.98% (3 significant figures)
