I NEED HELP ASAP!!!!!

1. Find the number of moles in 508 g of ethanol (C2H6O).
2. Calculate the volume, in liters, of 1.50 mol CI2 at STP

Answer 1

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

Step-by-step 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}=(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 =
`(22.4)/(1)* 1.50=33.6L` of volume

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

Answer 2

Answer: 1. 11.04moles

2. 33.6L
