Question

a 4.369g sample of metal is placed in a flask. water is added to the flask and the total volume in the flask is read to be 126.4ml. the mass of the water, flask, and metal is 268.5g. if the mass of the flask is 139.3g and the density of water is 1.000g/ml, the density of the solid is

Answer 1

density = mass/volume. You know the mass from the problem, directly. The rest of the problem is about finding the volume.
268.5 = mass flask, H2O, metal
-139.3 = mass flask
-4.369 = mass meal
-----------------
ansxxgrams = mass H2O
Volume H2O = mass H20/density H2O = about 124 something. But the problem states that the total volume (with the solid) is 126.4; therefore, volume of the solid is 126.4-124 something.

Then density of Metal = mass metal/volume metal

Answer 6

A 4.369 g sample of metal is placed in a flask. Water is added to the flask and the total volume in the flask is read to be 126.4 mL. The mass of the water, flask, and metal is 268.5 g. If the mass of the flask is 139.3 g and the density of water is 1.000 g/mL, what is the density of the solid in g/cm3.
