You are given CuSO
Strategy: First find the weight of hydrated copper sulfate in grams per mole. Then, using that discovery as a conversion factor, find the number of moles in 100 grams.
Weight of hydrated copper sulfate
Step 1. Get the atomic mass and number of each atom per molecule
Cu: 1 copper atom at 63.456 g/mol
S: 1 sulfur atom at 32.06 g/mol
#""_4#: 4 oxygen atoms at 15.999 g/mol
#""_2#): 10 hydrogen atoms at 1.008 g/mol
5(O): 5 oxygen atoms at 15.999 g/mol
Step 2. Multiply and add the terms of get the number of moles found in one gram.
The number of moles
Step 3. Multiply 100 grams times that result as a conversion factor.
Because 1 mole is equivalent to
