The part pictured here seems to be 3069px7 with the base color incorrectly set to white. In any case, it’s 3069, the standard 1x2 tile. Thanks to the folks at LDraw who have modeled every Lego brick in detail (because of course people have done that), we get a volume of 303.8mm³, with a bounding box size of 408.6mm³, for a density of about 74%. But, Bricklink can just directly tell us the mass of a 1x2 tile is 0.26g, so the total mass is 10.5 metric tons.

Of course someone has just published a table with all know masses of all lego pieces ever
That’s exactly the weight value I used in my original calculation :)
