Question

Here is a description of an experiment to measure the density of salty water. Step 1: An empty measuring cylinder was placed on an electronic balance. The reading on the balance was recorded (54.0 g). Step 2: Salty water was poured into the measuring cylinder. The new reading on the balance was recorded (115.2 g). Step 3: The volume of the salty water was read from the measuring cylinder (60 cm^3). Calculate the mass of the salty water.

Answer 1

The mass of the salty water is 61.2 grams, calculated by subtracting the mass of the empty measuring cylinder (54.0 g) from the total mass after adding the salty water (115.2 g).

Step-by-step explanation:

To calculate the mass of the salty water, we need to subtract the mass of the empty measuring cylinder from the total mass recorded after the salty water was added. With the recorded weight of the empty cylinder being 54.0 g and the combined weight being 115.2 g, the mass of the salty water can be found as follows:

Mass of salty water = Total mass - Mass of empty cylinder

= 115.2 g - 54.0 g

= 61.2 g

Therefore, the mass of the salty water is 61.2 grams.
