PCl₅ reacts upon contact with water to launch hydrogen chloride and supply phosphorus oxides. the primary hydrolysis product is phosphorus oxychloride PCl₅ + H₂O ========> POCl₃ + 2HCl.
Phosphorus trichloride appears as a colorless or slightly yellow fuming liquid with a pungent and irritating odor resembling that of hydrochloric acid. Causes severe burns to skin, eyes and mucous membranes.
Divide the mass of the material through its molar mass. The molar mass of a substance is the mass in grams of 1 mole of that substance. This mass is given via the atomic weight of the chemical unit that makes up that substance in atomic mass units.
One mole is described as the amount of substance containing as many number one entities atoms, molecules, ions, electrons, radicals, and lots of others. As there are atoms in 12 grams of carbon - 12(6. 023×10²³. The mass of one mole of a substance equals to its relative molecular mass expressed in grams.

Given the molecular formula of aspirin, C₉H₈O₄, in 1.50 moles of aspirin there are 13.5 moles of carbon.
<h3>What is a mole?</h3>
The mole is the SI base unit for the amount of matter. 1 mole of particles contains a number of Avogadro's particles.
We have 1.50 moles of aspirin, C₉H₈O₄. According to the molecular formula, the molar ratio of C₉H₈O₄ to C is 1:9.
1.50 mol C₉H₈O₄ × (9 mol C/1 mol C₉H₈O₄) = 13.5 mol C
Given the molecular formula of aspirin, C₉H₈O₄, in 1.50 moles of aspirin there are 13.5 moles of carbon.
