Calculate the atomicity of mercury molecules from the following data :
(a) 10.0 g of mercury combine with 0.8 g of oxygen to form an oxide.
(b) 500 mL of mercury vapour at S.T.P. weigh = 4.465g
(c) Specific heat of mercury is 0.033.

Explanation

To calculate the atomicity of mercury (Hg) from the given data, we will follow these steps:

### Step 1: Calculate the Equivalent Mass of Mercury
From the first piece of data, we know that 10.0 g of mercury combines with 0.8 g of oxygen.

The equivalent mass of mercury can be calculated using the formula:
\[
\text{Equivalent mass of Hg} = \frac{\text{Mass of Hg}}{\text{Mass of O}} \times \text{Equivalent mass of O}
