You sure its not supposed to be "mg"? Where'd you get the formula from?

It was in the Kaplan practice test solutions.

I thought it was mg.

The w isn't a subscript, like Mw for Mass of water?

Oh is could be that. I think you are right

This is correct. mg=pVg.

Are you saying that Mw means the Mass of water?

Mwg = pVg. Here the w is a subscript of M which indicates that the M is the mass of "w"ater. Weight of the water displaced is equal to the buoyant force.
