WebThe mass (in grams) of a compound is equal to its molarity (in moles) multiply its molar mass: grams = mole × molar mass. E.g. Molar mass of NaCl is 58.443, how many grams is 5 mole NaCl? grams = 58.443 × 5 = 292.215 (g) Molar mass of AgNO3 is 169.873, 2 kg AgNO3 is equal to how many moles? WebApr 3, 2024 · From the chemical formula 1 mole of the compound has 8 atoms of oxygen. So, it can be written as. 1 mole Cr3 (PO4)2 has 8 atoms of oxygen. 92.3 moles of Cr3 (PO4)2 has x atoms of oxygen. =. x = 8 x 92.3. x = 738.4 atoms. There will be 739 oxygen atoms in the 92.3 moles of Cr3 (PO4)2. Advertisement.
