How many Cs atoms are there in a 53.7 gram sample of Cs?
This is a two-step calculation. First convert grams Cs to moles Cs. Then convert moles Cs to atoms Cs.The atomic weight of cesium is 133 g/mol1. To convert grams to moles:moles Cs= 53.7 g Cs1 mol = 0.404 mol Cs133 gMultiply by moles per gram. Grams cancel out.2. To convert moles to atoms:atoms Cs = 0.404 mol Cs6.02 x 1023 atoms = 2.43E+23 atoms CsmolMultiply by atoms/mole. Moles cancel out.
