If mass stays the same and density decreases then volume?

Then the density increases. If you have 10 grams of mass for 5 mL of volume, then the density is 2 g/mL If you keep 10 grams of mass but 2mL of volume, then the density is 5 g/mL


What happens to density if the volume remains constant but mass increases?

Density = mass/volume. If you increase the volume but the mass remains the same the denominator will become larger while the numerator reamins the same. This will cause the fraction to become smaller and thus the density will decrease. In short the density will decrease!


What is the volume of 12.8 grams of a liquid that has a density of 0.789 grams?

Density = Mass/Volume so Volume = Mass/Density. Having said that, density is not measured in grams so it cannot be 0.789 grams. As a result, the question cannot be answered.


What would take up more space 5 grams of wood with a density of 0.9185g or 5 grams of gray blocks with a density of 1.42 g?

density is a measure of mass(weight)/ volume as the density of a specific mass increases the volume necessarily shrinks. Thus a lower density for a given mass indicates that mass has a greater volume. The wood therefor takes up more space, or volume, in this example.


How can the density of a liquid be measured?

The definition of density is mass per unit volume. Thus, you measure the volume of a liquid in mls, and then weight that volume in grams. You thus obtain grams/volume, and that is the density expressed as grams per ml.


How could you find the density of a potato?

first, you weigh it to get its mass. then you acquire its volume, since it has an irregular shape, you apply water displacement method. get a calibrated cylinder, note the initial water level and gently drop the potato in. measure the resulting water level and subtract it with the initial water level. this is your volume. density= mass/volume simply divide what you measured in grams with the volume of the potato (cm3). unit of density is grams per cubic centimeter or g/cm3


What is the density of an object which has a mass of 5 grams and a volume of 10cm3?

density = mass/volume density = 5/10 = 0.5 grams per cubic centimeter


What is the density of a material that is 15.00 grams and a volume of 5.0cm3?

Density = Mass/ Volume = 15/5 = 3 grams per cm3


What would be the density of object that has a volume of 25 and of 5 grams?

What would be the density of an object that has a volume of 25 cm3 and 5 grams?


What is the density of a sample that has a mass of 36 grams and a volume of 12 milliliters?

Density = mass/volume, so:36 grams/ 12 milliliters3 grams/ milliliter


What would be the volume of 20 grams of liquid if it has a density of 2.5 grams?

As density is measured in mass per unit volume, the question is unanswerable as written. We need to know "density of 2.5 grams per what measure of volume" in order to answer the problem.


What is the density of a solid that is 65.1 grams and 43.1cm?

Density is Mass/Volume. Since the mass is 65.1grams and the volume is 43.1cm, the density is 65.1/43.1 grams per cm. So the answer is 1.51044 grams/cm
