Question

Можете мне найти Mr для: (NH4) 2SO4

Answer 1

Mr((NH4)2SO4) = 14 × 2 + 1 × 8 + 32 + 16 × 4 = 132

Answer 2

Mr stands for Molar mass. It is the mass of a given substance divided by the amount of substance. In the case of (NH4)2SO4, we can calculate the molar mass by adding up the atomic masses of each element in the compound.

The molar mass of (NH4)2SO4 can be calculated as follows:

- The molar mass of nitrogen (N) is approximately 14.01 g/mol. - The molar mass of hydrogen (H) is approximately 1.01 g/mol. - The molar mass of sulfur (S) is approximately 32.07 g/mol. - The molar mass of oxygen (O) is approximately 16.00 g/mol.

To calculate the molar mass of (NH4)2SO4, we multiply the atomic masses of each element by the number of atoms present in the compound and then sum them up:

Molar mass of (NH4)2SO4 = (2 * molar mass of N) + (8 * molar mass of H) + molar mass of S + (4 * molar mass of O)

Molar mass of (NH4)2SO4 = (2 * 14.01 g/mol) + (8 * 1.01 g/mol) + 32.07 g/mol + (4 * 16.00 g/mol)

Molar mass of (NH4)2SO4 = 132.14 g/mol + 8.08 g/mol + 32.07 g/mol + 64.00 g/mol

Molar mass of (NH4)2SO4 = 236.29 g/mol

Therefore, the molar mass of (NH4)2SO4 is approximately 236.29 g/mol.
