9966 [12]

Answer:

1.76 g/mL

Explanation:

You need to find the volume.  You can do this by subtracting the volume of the water and the rock by the volume of the water.

72.7 mL  -  50 mL  =  22.7 mL

Now that you have volume, divide the mass by the volume to find the density.

39.943 g/22.7 mL = 1.76 g/mL
