Calculate the mass of Sulphur present in 3 gram of sulphur SO2​

To calculate the mass of Sulphur in 3 grams of SO2, we need to follow these steps:

1. First, we need to find the molar mass of SO2. The molar mass of Sulphur (S) is approximately 32.06 g/mol and the molar mass of Oxygen (O) is approximately 16.00 g/mol. Since there are two Oxygen atoms in SO2, we multiply the molar mass of Oxygen by 2. So, the molar mass of SO2 is 32.06 g/mol (for S) + 32.00 g/mol (for O2) = 64.06 g/mol.

2. Next, we need to find the mass percentage of Sulphur in SO2. The mass percentage is calculated by dividing the molar mass of Sulphur by the molar mass of SO2 and then multiplying by 100. So, the mass percentage of Sulphur in SO2 is (32.06 g/mol ÷ 64.06 g/mol) x 100 = 50.01%.

3. Finally, we can find the mass of Sulphur in 3 grams of SO2 by multiplying the mass of SO2 by the mass percentage of Sulphur. So, the mass of Sulphur in 3 grams of SO2 is 3 g x 50.01% = 1.50 g.

So, there is approximately 1.50 grams of Sulphur in 3 grams of SO2.
