The mass is 40 g.
Density is the mass per unit of volume of a substance. The equation to calculate density is:
density = mass/volume
In this question, you are given the density and the volume of a substance, and requires you to determine the mass.
Rearranging the density formula:
mass = density x volume
mass = 2 g/mL x 20 mL = 40 g

How do you find the density of liquid?
To find the density of a liquid, you would need to measure the mass of a specific volume of the liquid using a balance, and then divide the mass by the volume. The formula for density is density = mass/volume. Density is typically expressed in units such as g/mL or kg/L.
Can you estimate that the mass of an object with a density of 2 grams per cubic centimeter and a volume of 98 cubic centimeters is about 4 grams?
Yes, the mass of an object with a density of 2 grams per cubic centimeter and a volume of 98 cubic centimeters would be about 196 grams.
What is the volume 45.6 grams of silver if the density of density is 10.5 grams ml?
To find the volume of silver, divide the mass by the density. 45.6 grams / 10.5 g/ml = 4.34 ml. Therefore, the volume of 45.6 grams of silver is 4.34 ml.
If the weight of a substance is 10 grams and it has a volume of 2 cm3 what is the density?
Density is calculated by dividing the mass of a substance by its volume. In this case, the density would be 10 grams divided by 2 cm3, which equals 5 grams per cubic centimeter (g/cm3). Density is a measure of how much mass is contained in a given volume of a substance, and it is often used to identify and characterize materials based on their physical properties.
A mechanical pencil has the density of 3 grams per cubic centimeter the volume of the pencil is 15.8 cubic centimeters what is the mass of the pencil?
Synthetic diamonds can be manufactured at a pressure of 600,000atm. If we took 2 L of gas at 1 atm, and compressed it with a pressure of 600,000 atm, what would the volume of the gas be?
