'The Sedimentary rock formed from years of sediments piling on top of it and being compressed.'
Protein would be the main one.
Molar mass of CuSO4 * 5 H2O
= 63.546 + 32 + 16*4 + 5*18
= 249.546 g/mol
Mass of water in that formula: 5 * 18 = 90 g/mol
Percent by mass of water = 90 / 249.546 = 36%
<span>So, 36% of your 8.22 g is water. 0.36 * 8.22= 2.95 g of water

Sand only bc the salt dissolved and sand doesn't
