If you want to express the concentration in terms of percent mass, then you would have to divide the mass of solute to the mass of solution, then multiply it by 100.

Mass of solute = 8.40 g
Mass of solution = 8.40+94.60 = 103 g

Percent Mass = (8.40/103)*100 = <em>8.16%</em>

What is the volume of a salt crystal measuring 1.64 x 10^-2m by 1.5 x 10^-2m by 4.8 x 10^-3
lubasha [3.4K]

Answer:

V = 1.2 × 10⁻⁶ m³

Explanation:

Volume is equal to length × width × height, since we are given these measurements in the question we can simply plug our numbers into the formula.

V = l × w × h

V = 1.64 x 10⁻² × 1.5 x 10⁻² × 4.8 x 10⁻³

V = 1.2 × 10⁻⁶ m³
