The molecular mass of octane is 114.22 g/mol. what is the mass of 22.05 mol of octane?

In this item, we are asked to calculate for the mass of 22.05 mole of octane given that its molecular mass is equal to 114.22 g/mol. To answer this item, we simply have to multiply the number of moles with the molecular mass. That is, (114.22 g/mol)(22.05 mol) which is equal to 2518.221 grams.

In order to compute the mass of a substance, we may simply mulitply the number of moles of the substance by the molar mass of the substance, since molar mass is mass per mole. Therefore, we get: 114.22 * 22.05 = 2,518.55 grams 2,518.55 grams of octane are present.

Ibelieve it's celsius. hope this .
