Question

A beaker with a mass of 13.739g is filled with 132.9mL of a liquid with a density of 1.094g/mL. What will be the total weight (g) of the beaker with the liquid inside?

Answer 1

For the liquid, do 1.094 x 132.9 to find mass for the liquid. Answer should be about 145.3926. Then add the mass of the beaker (13.739) to get about 159.1316 g. Since the lowest amount of significant digits is 4 in the calculations, it rounds to 159.1 g total.

Answer 2

The total mass = 159.129

Step-by-step explanation:

Comment

The easiest way to do this is to set up a small table. The table contains 6 entrys: Three are meant to find the mass of the liquid and one states the mass of the beaker and 1 gives the answer. The table is given under this statement.

Solution

Mass of beaker 13.739

Volume = 132.9

density = 1.094 g/mL

Mass liquid = density * Volume

Mass = 1.094 g /mL *132.9 = 145.39

Total Mass = 159.129
