Density = mass / volume
You are given the density and the [v]olume, you can solve for the mass,
mass = density * volume
but first you need to convert the volume from units of km^3 to m^3.
1 km^3 = 1000 m * 1000 m * 1000 m
1 km^3 = 1 E9 m^3
mass = 3340 kg/m^3 * 2.2 E19 m^3
mass = 7.35 E22 kg.

change the volume to m^3. I think you would just multiply by 1000^3. Then multiply the density and volume so the the m^3 cancel. Yea, that gets you the 7.348e22kg.

Ozauary has the formula wrong...
M = D X V.
Make sure to convert the km^3 to m^3 before calculating...

density = mass/ vol,
therefore mass = density*vol.
i presume you mean volume and not colume

3340kg/m^3- times -2.2e10km^3.
my guess 7.35 E25 kg or something close to that
