Answer:

The volume is 50, 74 l

Explanation:

We use the formula PV = nRT. The temperature in Kelvin is = 273+ 20 =293K

PV=nRT ---> V = (nRT) / P

V= (2.0 mol x 0,082 l atm /K mol x 293 K) / 0,947 atm

V=50,74128828 l

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
