How many grams of cobalt(II) sulfate, , must be dissolved to prepare 200. mL of a 0.207 M aqueous solution of the salt? g
Added by Iker C.
Step 1
The molar mass of CoSO4 is: Co: 1 atom x 58.93 g/mol = 58.93 g/mol S: 1 atom x 32.07 g/mol = 32.07 g/mol O: 4 atoms x 16.00 g/mol = 64.00 g/mol Total molar mass = 58.93 + 32.07 + 64.00 = 155.00 g/mol Show more…
