Hi, I’m not sure if I did these right. Looking at the last question, what density was I supposed to use? liquid water or ice?

Hello - hope you're well
use the density of the ice to find the mass of the H2O present, then convert this mass into a volume for liquid water;

3*0.917 = 2.751g of H2O (volume x density)
2.751/1 = 2.752cm^3 (mass/density)

hope that helps
