WebQUESTION 1 Consider the following chemical equation: M + CaBr2 + MBr + Ca (M = unknown metal) When 269.79 g of M completely reacted with CaBr2.959.45 g of products (i.e., MBr + Ca) were produced. WebN (P2O5) = NA*m (P2O5)/M (P2O5) = 6.022x1023*0.27/142 = 1.145x1021 molecules So the total number of atoms is: N (Atoms) = 7* N (P2O5) = 7*1.145x1021 = 8.015x1021 molecules Answer : Total number of atoms is 8.015x1021 molecules.
