Question

An empty beaker has a mass of 52.148g. After placing 5.11mL into the beaker, the beaker and liquid have a combined mass of 61.731g. Calculate the density of the liquid (in g/mL).

Answer 1

To calculate the density of the liquid, subtract the mass of the empty beaker from the combined mass to get the mass of the liquid (9.583 g), then divide it by the volume of the liquid (5.11 mL) to find the density, which is 1.875 g/mL.

Step-by-step explanation:

The student is asking to calculate the density of a liquid given the mass of the empty beaker, the combined mass of the beaker with the liquid, and the volume of the liquid added. To find the density, we use the formula density (D) = mass (m) / volume (V). We first need to calculate the pure mass of the liquid by subtracting the mass of the empty beaker from the combined mass. Then, divide the mass of the liquid by its volume to obtain its density.

Calculation:

• Mass of the liquid = 61.731 g (combined mass) - 52.148 g (mass of empty beaker) = 9.583 g
• Density of the liquid = Mass of the liquid / Volume of the liquid
• Density = 9.583 g / 5.11 mL = 1.875 g/mL

Therefore, the density of the liquid is 1.875 g/mL.
