A compound which contains one atom of X and two atoms of Y for each three atoms of Z is made by mixing 5.0 g of X, 1.15×1023 atoms of Y and 0.03 g−atoms of Z. If only 4.40 g of the compound results, then the value of atomic mass of Y is (The atomic masses of Xand Z are 60 and 80, respectively and take avogadro number as 6×1023.)70 |
