7.6 g/ml
20.5 ml -20.0ml=.5ml
(3.8g)/(.5ml)=7.6g/ml
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
I assume the correct units for the density is 3.14 grams per milliliter. So if you have 93.5 grams of a substance with a density of 3.14 grams per milliliter, then you divide the mass by the density to find volume. 93.5 grams/3.14 grams/ml = 29.77 ml
Density = Mass/Volume So Volume = Mass/Density = 45.6g / 10.5 g per ml = 45.6/10.5 ml = 4.34 ml (to 2 dp)
The volume is 19,245 cm3.
Density = (mass) / (volume) = 20/4 = 5 grams per cc
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
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!
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.
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.
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.
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
density = mass/volume density = 5/10 = 0.5 grams per cubic centimeter
Density = Mass/ Volume = 15/5 = 3 grams per cm3
What would be the density of an object that has a volume of 25 cm3 and 5 grams?
Density = mass/volume, so:36 grams/ 12 milliliters3 grams/ milliliter
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.
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
