What is the mass of 1kg water when it forms ice? If the density of ice is 0.9 × 10 cubic meter, the volume of 1kg water when it forms ice will be larger cubic metre?

What is the mass of 1kg water when it forms ice? If the density of ice is 0.9 × 10 cubic meter, the volume of 1kg water when it forms ice will be larger cubic metre?

Water forms ice and its mass remains unchanged at 1kg
V=m/ρ=1kg/0.9*10^3kg/m^3=1.111dm^3
