Calculating Molar Mass of Cu2SiO3

To calculate the molar mass of a compound, we need to consider the atomic masses of each element present in the compound and then sum them up.

The molar mass of Cu2SiO3 can be calculated as follows:

- The atomic mass of copper (Cu) is approximately 63.55 g/mol. - The atomic mass of silicon (Si) is approximately 28.0855 g/mol. - The atomic mass of oxygen (O) is approximately 16.00 g/mol.

Now, let's calculate the molar mass of Cu2SiO3:

Molar mass of Cu2SiO3 = (2 * atomic mass of Cu) + atomic mass of Si + (3 * atomic mass of O)

Molar mass of Cu2SiO3 = (2 * 63.55 g/mol) + 28.0855 g/mol + (3 * 16.00 g/mol)

Molar mass of Cu2SiO3 = 127.1 g/mol + 28.0855 g/mol + 48.00 g/mol

Molar mass of Cu2SiO3 = 203.1855 g/mol

Therefore, the molar mass of Cu2SiO3 is approximately 203.1855 g/mol.
