Question

How many moles are present in 100. g of aspirin (C2H804, molar mass 180.2 g/mol)? 0.555 mol of aspirin 1.80 mol of aspirin 18.0 mol of aspirin 100. mol of aspirin

Answer 1

Answer:

0.555 mol of aspirin

Explanation:

Given,

Mass of aspirin = 100 g

Molar mass of aspirin = 180.2 g/mol

To find, moles of aspirin in 100 g of mass = ?

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{100\ g}{180.2\ g/mol}$

Moles of aspirin in 100 g = 0.555 moles
