Answer to Question #100433 in Chemistry for jury

Question

what is the mass of 0.200 moles of aspirin

Answer 1

According to the equation:

m = n × Mr,

where m - mass, n - number of moles, Mr - molecular weight.

As the molecular weight of aspirin is 180 g/mol, the mass of 0.200 moles of aspirin equals:

m (aspirin) = n (aspirin) × Mr (aspirin) = 0.2 mol × 180 g/mol = 36 g.

Answer: 36 g
