It has to be one of these:
2 g
2 mL/g
2 g/mL
2 mL/g
It is 2 g/mL.
mg
The right answer is 2g/ml
2g
F
Density is the measure of mass per unit volume. Volume cannot be measured in centimetres (cm). Without a measure of volume, the answer is indeterminate.
The volume of a sample of water is 20 cm3. The mass of this sample is closest to
density = mass / volume =190 / 20 =9.5g/cm3
Density = (mass) / (volume) = 20/4 = 5 grams per cc
density = mass/volume = 20/5 = 4 g/cm3
The volume of the sample whose mass is 20 g and density is 4 g/ml is 5 milliliters.
The idea is to divide the mass by the volume.
Density is the measure of mass per unit volume. Volume cannot be measured in centimetres (cm). Without a measure of volume, the answer is indeterminate.
Density is defined as mass / volume. Solving for mass: mass = density x volume In other words, all you have to do is multiply the density times the volume, to get the mass. Answer:0.8 mg
The volume of a sample of water is 20 cm3. The mass of this sample is closest to
21.5 g/cm cubed
Density = Mass / Volume So, density of an object with a volume of 10ml and a mass of 20 grams is = m / v = 20grams/10ml = 2g/ml
density = mass / volume =190 / 20 =9.5g/cm3
density = mass/volume density = 15/20 = 3/4 units/ml
You cannot. Density = Mass/Volume so without the volume of the substance in question, you cannot convert mass into density.
Density = (mass) / (volume) = 20/80 = 0.25 g/cc
density = mass/volume = 40/20 = 2 g/cc
