Answer: There are 6 moles of carbon atom present in 3 moles of dimethylsulfoxide
Step-by-step explanation:
We are given:
A chemical compound named dimethylsulfoxide having chemical formula of

In 1 mole of dimethylsulfoxide, 2 moles of carbon atom, 6 moles of hydrogen atom, 1 mole of sulfur atom and 1 mole of oxygen atom is present.
We need to calculate the number of moles of carbon present in 3 moles of dimethylsulfoxide
So, in 3 moles of dimethylsulfoxide,
moles of carbon atom,
moles of hydrogen atom,
moles of sulfur atom and
moles of oxygen atom are present.
Hence, there are 6 moles of carbon atom present in 3 moles of dimethylsulfoxide
