The new metamorphic rock would have the approximate same mass as the igneous rock.

Explanation:

The best expression for the transformation would be that the "the metamorphic rock would have the approximate same mass as the igneous rock".

Igneous rocks are rocks formed from the cooling and solidification of molten magma.
To transform to metamorphic rocks, mineralogical changes at high pressure and temperature occurs in them.
This changes does not lead to any differences in the mass of the rock.
The volume of the rock might likely change and the density increases.
The mass will approximately remain fairly constant.
