Question

A student obtains the following data: Mass of empty, dry graduated cylinder: 25.938 g Volume added of NaCl solution: 6.515 mL Mass of graduated cylinder + NaCl solution: 39.895 g What is the density of the solution? Express your answer to 3 digits after the decimal.

Answer 1

Density=2.142 g/mL

Step-by-step explanation:

Density is defined as the mass per unit volume of a compound, the mass of the NaCl solution is given by the subtraction of the mass of the cylinder with the solution minus the mass of the empty dry cylinder.

`Density=d=(m)/(v) =((39.895-25.938)g)/(6.515mL) = 2.142(g)/(mL)`
