Ms. bristol measured the mass of a closed beaker containing several ice cubes. the mass was 100 g. an hour later, after the ice cubes had melted, ms. bristol measured the mass of the beaker again. what was the mass of the beaker the second time? * a. 75 g b. 100 g c. 125 g d. 150 g

I mean..this is a really subjective question
This question is just bad..fundemantally.Like.
What was the mass of the beaker?
What was the mass of the ice alone?
what was the mass of the supposed lid used to cover the beaker?
Was the room left in room tempretature?.
Is the mass of the water formed during condensation negligible?
Going with logic it should be 100g

The formula is (nh4)2co3
