europium crystallizes in a body-centered cubic cell (the Eu atoms occupy only lattice points). calculate the mass of the unit cells

metallic iron crystallizes in a cubic lattice. The unit cell edge length is 287 pm. The density of iron is 7.87 g/cm^3. Calculate the mass (in grams) of one unit cell

calculate the amount of energy (in kj) necessary to convert 457 g of liquid water from 0 Celecius to water vapor at 167 celcius. the molar heat of vaporization (Hvap) of water is 40.79 jk/mol. the specific heat for water is 4.187 j/g celcius and for steam...
