Question

A beaker with a mass of 135.8 g is filled with chloroform (d = 1.48 g/cmˆ3) and the mass of the beaker and its contents is 288.2 g. What volume of chloroform was added to the beaker (in mL)?

a) 98.4 mL
b) 289.6 mL
c) 152.7 mL
d) 103 mL

Answer 1

To find the volume of chloroform added to the beaker, subtract the mass of the empty beaker from the total mass. Then, use the density of chloroform to calculate the volume. The volume of chloroform added to the beaker is 103 mL.

Step-by-step explanation:

To calculate the volume of chloroform added to the beaker, we need to find the mass of chloroform. We can do this by subtracting the mass of the empty beaker from the total mass of the beaker and its contents. The mass of chloroform is 288.2 g - 135.8 g = 152.4 g.

Next, we can use the density of chloroform to calculate its volume. Density is defined as mass divided by volume, so we can rearrange the formula to solve for volume: volume = mass / density. Using the given density of chloroform (1.48 g/cm³), we can calculate the volume: volume = 152.4 g / 1.48 g/cm³ = 103 cm³.

Since 1 cm³ is equal to 1 mL, the volume of chloroform added to the beaker is 103 mL. Therefore, the correct answer is d) 103 mL.
