Explanation:
By unit conversion, the aspirin contains 7.72 grains.
We need to know about unit conversion to solve this problem. The unit conversion can be used to convert a unit to another unit. It can be defined as
a = xb
where a is unit a, b is unit b and x is the constant of conversion.
From the question above, we know that
m = 0.5 gram
unit conversion
(1 grain = 64.8 mg)
Convert the unit conversion to 1 mg
1 grain = 64.8 mg
1/64.8 grain = 64.8/64.8 mg
1 mg = 1/64.8 grain
Convert the aspirin mass to grain
m = 0.500 g
m = 0.5 x 10³ mg
m = 0.5 x 10³ x 1/64.8 grain
m = 7.72 grain

Physical change: a change in which no new substances are formed. the form of the substance is changed but not it's chemical composition (ice melting, bread toasting)
chemical change: any change that results in the formation of new chemical substances. this type of change modifies molecules and atoms by making and breaking the bonds between atoms! (iron rusting, gas burning)
so basically a physical change just changes the appearance of a substance, but a chemical change changes the makeup on a molecular level. i hope this helps you out!
