Final answer:
The density of a liquid with a mass of 31.1415 g and a volume of 30.13 cm³ is calculated by dividing the mass by the volume, resulting in a density of 1.033 g/cm³.
Step-by-step explanation:
The density of a liquid can be calculated using the mass and volume of the liquid. The formula to calculate density is Density = Mass / Volume. To measure the volume of a liquid accurately, it is important to look at the bottom of the meniscus, which is the lowermost part of the curve seen at the top of the liquid when it is in a graduated cylinder.
For the given mass of 31.1415 g and a volume of 30.13 cm³, the calculation for density would be Density = 31.1415 g / 30.13 cm³.
Now, let's perform the calculation:
Density = 31.1415 g / 30.13 cm³
Density = 1.033 g/cm³ (rounded to three decimal places)
Therefore, the density of the liquid is 1.033 g/cm³.
