Find the Mass of 1 Mole 1.5mol of H_2O

To find the mass of ${\displaystyle 1}$ mole of ${\displaystyle 1.5\mathrm{mol}}$ look up the atomic mass of each element and multiply it by the number of atoms contained in each element in the molecule.

mass of ${\displaystyle 1}$ mole of ${\displaystyle 1.5\mathrm{mol}}$${\displaystyle =}$${\displaystyle \left(\text{mass of U}\right)}$+${\displaystyle \left(\text{mass of N}\right)}$+${\displaystyle \left(\text{mass of I}\right)}$+${\displaystyle \left(\text{mass of T>mol}\right)}$

Fill in the atomic masses from the periodic table.

mass of ${\displaystyle 1}$ mole of ${\displaystyle 1.5\mathrm{mol}}$${\displaystyle =}$${\displaystyle \left(238.02999877\right)}$+${\displaystyle \left(14.01000022\right)}$+${\displaystyle \left(126.90000152\right)}$+${\displaystyle \left(0\right)}$
