Question

2.295 g of the oxide of a bivalent metal when dissolved in nitric acid form 3.915 g of the nitrate of the metal. Calculate the atomic weight of the metal.

Answer 1

Explanation:

For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.

actually I don't know the answer for this question but still I can help you how to find it.....
