It is known that the density of water is 1.0 × 10 ^ 3kg / m ^ 3 and the density of ice is 0.9 × 10 ^ 3kg / m ^ 3. The mass of ice is () kg after the water of 1m ^ 3 solidifies into ice

It is known that the density of water is 1.0 × 10 ^ 3kg / m ^ 3 and the density of ice is 0.9 × 10 ^ 3kg / m ^ 3. The mass of ice is () kg after the water of 1m ^ 3 solidifies into ice

No matter what it becomes, the mass is constant, so the mass of ice is the mass of water
M = water density × water volume = 1.0 × 10 ^ 3kg / m ^ 3 × 1m ^ 3 = 1.0 × 10 ^ 3kg
