A chemist conducted a precipitation reaction in which they added 35.5 mL of 0.125 M copper(II) sulfate to 50.00 mL of 0.150 M sodium hydroxide. The anion that was left over was subsequently precipitated by adding calcium chloride to the reaction mixture. What mass of the calcium chloride was added

Respuesta :

The mass of CaCl2 is 0.076gram.

The molar mass of a compound is just the molar hundreds of every detail inside the compound brought up. Since the molar mass of Calcium is 40.08 g and the molar mass of Chlorine is 35.45, it might be 40g.08g+35.45g+35.45g (with 2 Chlorines in step with the subscript.) That leaves you with 110.98 g

Calcium and chlorine are the 2 factors in our instance. The molar loads of Ca (forty.08g/mol) and Cl (35.45g/mol) need to then be determined. Now that we have the masses of calcium and each chlorine atom, we are able to truly place them together to get the whole compound's molar mass, which is a hundred and 10.98 g/mol.
