mass is conserved (total mass is the sum of the mass of the constituents) so 50 + 50 = 100g
50
mass percent=g solute/ g solute=g solvent X 100% mass percent = 50g/ 50g+1000g X100%= 4.76%
20g I think

density = mass/volume = 50g/8cm^3 = 6.25 g/cm^3
That is 1.764 ounces.
Mass of the object is 200g + 50g + 6.8g = 256.8g
The question isn't valid because a gram is a unit of mass but a milliliter is a unit of volume. You would need to refer to a specific material's density to make a comparison. Density relates the volume of a material to its mass, but it can differ greatly based on the material in question. For example, 50g of lead occupies much less volume than 50g of water.
2.4 kg
An experiment where 50g of sugar are burned down to 20g is explained by CO2 being formed during combustion that leaves the sugar.
(50g)/(15g/cm3)=3.333...cm3 or 3 1/3 cm3
