Answer 2

Calculation of Number of Molecules in Ca(H2PO4)2

To calculate the number of molecules in Ca(H2PO4)2, we can use Avogadro's number and the given mass of Ca(H2PO4)2.

The molar mass of Ca(H2PO4)2 can be calculated as follows: - The molar mass of Ca = 40.08 g/mol - The molar mass of H = 1.01 g/mol - The molar mass of P = 30.97 g/mol - The molar mass of O = 16.00 g/mol

Using these values, we can calculate the molar mass of Ca(H2PO4)2: Molar mass of Ca(H2PO4)2 = (1 * 40.08) + (2 * 1.01) + 30.97 + (4 * 16.00) g/mol Molar mass of Ca(H2PO4)2 = 136.08 g/mol

Now, we can use Avogadro's number to calculate the number of molecules in a given mass of Ca(H2PO4)2.

Calculation:

Given mass of Ca(H2PO4)2 = 1 mole Molar mass of Ca(H2PO4)2 = 136.08 g/mol

Using Avogadro's number: 1 mole of Ca(H2PO4)2 contains 6.022 x 10^23 molecules.

Therefore, the number of molecules in Ca(H2PO4)2 is 6.022 x 10^23.

This calculation is based on the molar mass of Ca(H2PO4)2 and Avogadro's number, which are fundamental concepts in chemistry.
