Before starting, we will convert all the givens into standard units as follows:
1.8 * 10^14 KJ/sec = 1.8 * 10^14 * 1000 = 1.8 * 10^17 J/sec
24 hours = 24 * 60 * 60 = 86400 second
Now, we are given that:
The earth receives 1.8 * 10^17 J/sec. We will begin by calculating the total energy received by the earth in 24-hours
Total energy = 1.8 * 10^17 * 86400 = 1.5552 * 10^22 Joules
Then we will get the mass from the following rule:
E = m * c^2 where:
E is the total energy = 1.5552 * 10^22 Joules
m is the mass we need to find
c is the speed of light = 3 * 10^8 m/sec
Substitute with the givens to get the mass as follows:
1.5552 * 10^22 = m * (3*10^8)^2
m = 172800 kg

The molecular formula of dimethyl sulfoxide is 
. Molar mass of dimethyl sulfoxide is 78.13 g/mol. Calculate number of moles as follows:
From the molecular formula, 1 mole of dimethyl sulfoxide contains 2 moles of Carbon, 6 moles of Hydrogen, 1 mole of Sulfur and 1 mole of oxygen.
Thus, 91.38 moles of dimethyl sulfoxide will have:
Carbon :
Hydrogen:
Sulfur:
Oxygen:
Since, 1 mole of an element equals to 
atoms thus, number of atoms can be calculated as:
Carbon:
Thus,
Hydrogen:
Thus,
Sulfur:
Thus,
Oxygen:
Thus,
Therefore, number of C, S, H and O atoms are 
respectively.
