If iron has a density of 7.87g/cm³ and a mass of 3.729g, then the volume of iron is 0.474cm³
HOW TO CALCULATE VOLUME:
- The volume of a substance can be calculated by dividing the mass by its density. That is;
Volume (mL) = mass (g) ÷ density (g/mL)
- The density of iron is given as 7.87g/cm³ while its mass is 3.729g of iron. Hence, the volume can be calculated as follows:
Volume = 3.729 ÷ 7.87
Volume = 0.474cm³
Therefore, the volume of iron is 0.474cm³

Answer:
As Per Given Information
Number of moles SO₂ ( Sulphur dioxide ) is 0.30
We 've been asked to find the number of atoms in given moles of Sulphur dioxide .
Value of Avogadro Number is 6.022 × 10²³ mol⁻¹
For finding the number of atoms we will use formale
Putting the given value we obtain
So, the number of atoms in sulphur dioxide is 1.8066 × 10²³
