Answer: 184g
Step-by-step 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
