2. Calculate the volume, in liters, of 1.50 mol CI2 at STP

Answer 1

Answer: 1. 11.04moles

2. 33.6L

Explanation:Please see attachment for explanation

Answer 2

Answer:

For 1: The number of moles of ethanol are 11.04 moles

For 2: The volume of chlorine gas at STP for given amount is 33.6 L

Explanation:

• For 1:

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Given mass of ethanol = 508 g

Molar mass of ethanol = 46 g/mol

Putting values in above equation, we get:

$\text{Moles of ethanol}=\frac{508g}{46g/mol}=11.04mol$

Hence, the number of moles of ethanol are 11.04 moles

• For 2:

We are given:

Moles of chlorine gas = 1.50 moles

At STP:

1 mole of a gas occupies 22.4 L of volume

So, 1.50 moles of chlorine gas will occupy = $\frac{22.4}{1}\times 1.50=33.6L$ of volume

Hence, the volume of chlorine gas at STP for given amount is 33.6 L
