Question

The molar mast of vanadium is 50 99415 What is its equivalent mass; when it reacts with chlorine to form VCI_5? When it reacts with HCI to form VCl_3? Same experiment was carried out using Ca and H_2 SO_4. Write the molecular equation for the reaction of Ca with H_2 SO_4. What volume of H_2, at standard conditions, will be liberated from the reaction of 0.0645 g of Ca with an excess of H_2 SO_4? Calculate the mass of aluminum metal that will liberate 45.02 ml of dry H_2 at standard conditions when reacted with an excess of HCl.

Explanation / Answer

1.

a. Equivalent mass = Molar mass / Valence

Equivalent mass of Vanadium in VCl6 = 50.99415 / 6 = 8.499025 g

b. Equivalent mass = Molar mass / Valence

Equivalent mass of Vanadium in VCl3 = 50.99415 / 3 = 16.99805 g
