How many low dose 81 mg aspirin tablets can be made from 1.21 kg of aspirin? 1.21kg=1210g=1.21*106mg

Answer:

convert 1.21 kg into mg

1 kg = 1000 g and 1g = 1000 mg, hence

1 kg = 10⁶ mg, in the same way 1.21 kg = 1.21 x 10⁶ mg

now we need a tablet with 81 mg, therefore divide 1.21 x 10⁶ mg by 81 to get number of low dose tablets we can made.

1.21 x 10⁶ mg / 81 = 14938.2716049, we can round-off to an integer as tablets are in integer numbers only not in fractions.

14938 aspirin tablets can be made from 1.21 kg of aspirin.
