Dimethyl sulfoxide [(ch3)2so], also called dmso, is an important solvent that penetrates the skin, enabling it to be used as a topical drug-delivery agent. calculate the number of c, s, h, and o atoms in 7.14 × 103 g of dimethyl sulfoxide.

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.
