Question

What is the density of a saline solution if 60.0 mL has a mass of 30.000g? (Please show a picture of the work!!)

Answer 1

Density=mass/volume =30/60= 0.5 (g/mL)
hope this helps 

Answer 2

Volume of solution is 60.0 mL and mass is 30.000 g.  Density of a solution is defined as mass per unit volume.

Thus, density can be calculated as follows:

d=\frac{m}{V} ….. (1)

Here, d is density, m is mass and V is volume.

Putting the value of mass and velocity in the equation (1),

d=\frac{30.000 g}{60.0 mL}=0.5 g/mL

Thus, the density of a saline solution is 0.5 g/mL.
