What is the mass of 4 moles of C2H6O?

Answer: 184g

Explanation:

To calculate moles

No of moles = mass given / molar mass

Molar mass of C2H60

C which is carbon is 12

H which is hydrogen is 1

O which is oxygen is 16

Looking at the element, we have 2c, 6h and 1 oxygen

Molar mass = 2 (12) + 6 (1) + 16

Molar mass = 24+6+16

Molar mass = 46g/m

So we have

No of moles = mass given/molar mass

Here we are looking for the mass, so

Mass = molar mass * no of moles

No of moles given is 4moles

Molar mass calculated is 46g/mole

Substitute the values

Mass = 4moles * 46g/moles

Mass = 184g

Mass of C2H60 = 184g
