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
Step-by-step explanation:
To calculate the number of moles, we use the equation:

Given mass of ethanol = 508 g
Molar mass of ethanol = 46 g/mol
Putting values in above equation, we get:

Hence, the number of moles of ethanol are 11.04 moles
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 =
of volume
Hence, the volume of chlorine gas at STP for given amount is 33.6 L
