Solution

The correct option is A
4.67%

Mass of the solute = 49g

Mass of the solution = mass of solvent + mass of solute = 1000g + 49g = 1049g

Thus, concentration of the solution = (mass of solute $\div$ mass of solution) x 100

= (49 $\div$ 1049) $\times$ 100 = 4.67%

If 49g of Sodium Chloride is added to 1000g of water. What is the concentration of the solution at room temperature?

The correct option is A 4.67% Mass of the solute = 49g Mass of the solution = mass of solvent + mass of solute = 1000g + 49g = 1049g Thus, concentration of the solution = (mass of solute ÷ mass of solution) x 100 = (49 ÷ 1049) ×100 = 4.67%

The correct option is A
4.67%

Mass of the solute = 49g

Mass of the solution = mass of solvent + mass of solute = 1000g + 49g = 1049g

Thus, concentration of the solution = (mass of solute $\div$ mass of solution) x 100

= (49 $\div$ 1049) $\times$ 100 = 4.67%
