Answer 2

% mass of a solution is the mass of the solute present per 100 g of solution. It can be calculated using the formula,

`Mass % = (Mass of solute (g))/(Mass of solution (g)) * 100`

Mass of solute = 4.92 g

Mass of solvent, water = 347 g

Total mass of solution = 347 g + 4.92 g = 351.92 g

Mass % of the solute =
`(4.92 g)/(351.92 g) * 100 = 1.398 %`

Therefore, the weight/weight % = 1.398 %
