Question

Aspirin has a density of 1.40 g/cm3 what is the volume in cubic centimeters of a tablet weighing 320 mg ?

Answer 1

Using the density formula, we have D=M/V, where D is the density, M is the mass, and V is the volume. Modifying this formula by algebra, we get V=M/D.

Now, take the mass (320 mg) and convert it to grams (g) so that you have equal units on both sides of the equation. Next, divide the converted mass by the density, and cancel out the grams due to division. You should have your volume, in cubic centimeters.

Answer 2

Answer: The volume of aspirin is
`0.23cm^`

Step-by-step explanation:

To calculate mass of a substance, we use the equation:

`\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}`

We are given:

Density of acetone =
`1.40g/cm^3`

Mass of aspirin = 320 mg = 0.320 g (Conversion factor: 1 g = 1000 mg)

Putting values in above equation, we get:

`1.40g/cm^3=\frac{0.320g}{\text{Volume of aspirin}}\\\\\text{Volume of aspirin}=0.23cm^3`

Hence, the volume of aspirin is
`0.23cm^`
