The question is incomplete. the complete question is:
A chemistry student needs 35.0 g of pentane for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of pentane is [tex]0.626 g/cm^3[/tex]. Calculate the volume of pentane the student should pour out.Round your answer to 3 significant digits.
Answer: The volume of pentane the student should pour out is 55.9 ml
Explanation:
Density is defined as the mass contained per unit volume.
To calculate volume of a substance, we use the equation:
[tex]\text{Density of pentane}=\frac{\text{Mass of pentane}}{\text{Volume of pentane}}[/tex]
We are given:
Density of pentane = [tex]0.626g/cm^3[/tex]
Mass of pentane = 35.0 g
Putting values in above equation, we get:
[tex]0.626g/cm^3=\frac{35.0g}{\text {Volume of pentane}}\\\\\text{Volume of pentane}=55.9cm^3=55.9ml[/tex]
(Conversion factor: [tex]1cm^3=1ml[/tex])
Hence, the volume of pentane is 55.9 ml
