It has to be one of these:
2 g
2 mL/g
2 g/mL
2 mL/g
In order to determine the mass of the water sample, you would need to know the density of water. The density of water is approximately 1 g/cm3. Therefore, the mass of a 20 cm3 sample of water would be 20 grams (20 cm3 * 1 g/cm3 = 20 grams).
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 = (mass) / (volume) = 20/4 = 5 grams per cc
The density of the unknown solid can be calculated using the formula: density = mass / volume. Substituting the values, we get density = 190 g / 20 cm3 = 9.5 g/cm3. Therefore, the density of the unknown solid is 9.5 g/cm3.
The density of the unknown solid is 20 g/ml. This is calculated by dividing the mass (40g) by the volume (2ml).
The volume of the sample whose mass is 20 g and density is 4 g/ml is 5 milliliters.
In order to determine the mass of the water sample, you would need to know the density of water. The density of water is approximately 1 g/cm3. Therefore, the mass of a 20 cm3 sample of water would be 20 grams (20 cm3 * 1 g/cm3 = 20 grams).
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 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.
The density of platinum can be calculated by dividing the mass by the volume. In this case, the density would be 430 g / 20 cm3 = 21.5 g/cm3.
To find the density of the liquid, use the formula density = mass/volume. Given that the mass is 25 g and the volume is 20 cm³, the density would be 25 g / 20 cm³ = 1.25 g/cm³. Therefore, the density of the liquid is 1.25 g/cm³.
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 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.
You do not give a value for the volume. Density is worked out by the following expression: density = mass/volume Your units will be g per ml
Density = (mass) / (volume) = 20/4 = 5 grams per cc
