5.85 g of sodium chloride(NaCl) is dissolved in 250 mL OF solution. Calculate mass percentage of the solute.

We need the density of the solution. Without it we can assume it is 250 g H2O + 5.85g NaCl.

Then %NaCl = [(mass NaCl)/mass soln]*100 = ?

To calculate the mass percentage of a solute in a solution, you need to determine the mass of the solute and the mass of the entire solution.

Given:
Mass of sodium chloride (NaCl) = 5.85 g
Volume of solution = 250 mL = 250 cm³

To find the mass of the entire solution, we need to consider the density of the solution, assuming it is the same as water (1 g/cm³).

Mass of the solution = Volume of the solution * Density of the solution
Mass of the solution = 250 cm³ * 1 g/cm³
Mass of the solution = 250 g

Now that we have the mass of both the solute (NaCl) and the solution, we can calculate the mass percentage of the solute.

Mass percentage = (Mass of solute / Mass of solution) * 100
Mass percentage = (5.85 g / 250 g) * 100
Mass percentage = 2.34%

Therefore, the mass percentage of sodium chloride (NaCl) in the solution is 2.34%.
