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.

Ok we can use boyle’s law (stating that P is proportional to V) to make the equation (P1V1) =(P2V2).
once we’ve done this, we can plug in the numbers:
(800•500) = (200•V2)
and then we get that
V2= 2000 ml

hope this helps!! :)
