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
. 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:
![\text{Density of pentane}=\frac{\text{Mass of pentane}}{\text{Volume of pentane}}](https://tex.z-dn.net/?f=%5Ctext%7BDensity%20of%20pentane%7D%3D%5Cfrac%7B%5Ctext%7BMass%20of%20pentane%7D%7D%7B%5Ctext%7BVolume%20of%20pentane%7D%7D)
We are given:
Density of pentane = ![0.626g/cm^3](https://tex.z-dn.net/?f=0.626g%2Fcm%5E3)
Mass of pentane = 35.0 g
Putting values in above equation, we get:
![0.626g/cm^3=\frac{35.0g}{\text {Volume of pentane}}\\\\\text{Volume of pentane}=55.9cm^3=55.9ml](https://tex.z-dn.net/?f=0.626g%2Fcm%5E3%3D%5Cfrac%7B35.0g%7D%7B%5Ctext%20%7BVolume%20of%20pentane%7D%7D%5C%5C%5C%5C%5Ctext%7BVolume%20of%20pentane%7D%3D55.9cm%5E3%3D55.9ml)
(Conversion factor:
)
Hence, the volume of pentane is 55.9 ml
