Question

A student obtains the following data: Mass of empty, dry graduated cylinder: 21.577 g Volume added of NaCl solution: 4.602 mL Mass of graduated cylinder NaCl solution: 39.664 g What is the density of the solution?

Answer 1

Answer: The density of NaCl solution is 3.930 g/mL

Step-by-step explanation:

We are given:

Mass of cylinder,
`m_1` = 21.577 g

Mass of NaCl and cylinder combined, M = 39.664 g

Mass of NaCl,
`m_2` =
`(M-m_1)=(39.664-21.577)g=18.087g`

To calculate density of a substance, we use the equation:

`\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}`

We are given:

Mass of NaCl = 18.087 g

Volume of NaCl solution = 4.602 mL

Putting values in above equation, we get:

`\text{Density of NaCl}=(18.087g)/(4.602mL)\\\\\text{Density of NaCl}=3.930g/mL`

Hence, the density of NaCl solution is 3.930 g/mL
