A typical aspirin tablet contains 5.00 grains of pure aspirin analgesic compound. The rest of the tablet is

Pavel [41]

Answer:

$Tablets=193$

Explanation:

Hello,

In this case, given that a typical aspirin tablet contains 5.00 grains of pure aspirin, the first step here is to compute the mass of those grans per tablet given that 1.00 g = 15.4 grains:

$m=5.00grains*\frac{1.00g}{15.4grains}=0.325g$

In such a way, the number of aspirin tablets are computed considering the total mass of aspirin and the mass per tablet:

$Tablets=\frac{62.7g}{0.325g}\\ \\Tablets=193$

Best regards.
