Question

5.85 g of nacl is dissolved in 500ml of solution. calculate a) the mass percentage of the solute

Answer 1

Answer:

Hello student,

When we dissolve 5.85g of NaCl in 500 ml of water then the molarity of the NaC l is 0.2M.

Explanation:-

The formula for molarity M is

M = mol v

The moles of sodium chloride is 5.85 58.4 ≈ 0.1 mol

The volume of water is 0.5 l

So

M = mol v = 0.1 0.5 = 0.2 M
