<u>**Answer:**</u>** The new volume of the gas will be 0.233L.**

<u>**Explanation:**</u>

To calculate the new volume of the gas, we will use the equation given by **Boyle's Law.**

The above law states that the pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

**Mathematically,**

**(At constant temperature and number of moles)**

or,

where,

are the initial pressure and volume of the gas.

are the final pressure and volume of the gas.

**We are given:**

**Putting values in above equation, we get:**

**Hence, the new volume of the gas will be 0.233L.**

**Answer:**

We need 226 grams of FeS

**Explanation:**

Step 1: Data given

Mass of FeCl2 = 326 grams

Molar mass FeCl2 = 126.75 g/mol

Step 2: The balanced equation

FeS + 2 HCl → H2S + FeCl2

Step 3: Calculate moles FeCl2

Moles FeCl2 = 326 grams / 126.75 grams

Moles FeCl2 = 2.57 moles

Step 4: Calculate moles FeS needed

For 1 mol H2S and 1 mol FeCl2 produced, we need 1 mol FeS and 2 moles HCl

For 2.57 moles FeCl2 we need 2.57 moles FeS

Step 5: Calculate mass FeS

Mass FeS = 2.57 moles * 87.92 g/mol

Mass FeS = 226 grams FeS

We need 226 grams of FeS
