A substance that has a mass of 20g and volume of 10cm3.
How much mass does one cm3 of this substance have?
A substance with a mass of 125g and a volume of 25cm3.
How much mass does one cm3 of this substance have?
Please tell me how to do this.
1. mass/cm^3 = Density = 20g/10cm^3 = 2g/cm^3 = 0.002kg/cm^3.
2. Density = 125g/25cm^3 = 5 g/cm^3 =
0.005kg/cm^3.
To calculate the mass of one cm3 of a substance, you need to divide the total mass of the substance by its total volume. Let's calculate it step by step using the given examples:
Example 1:
Given: Mass = 20g, Volume = 10cm3
1. Divide the mass by the volume: 20g ÷ 10cm3 = 2g/cm3
The substance has a mass of 2g per 1 cm3.
Example 2:
Given: Mass = 125g, Volume = 25cm3
1. Divide the mass by the volume: 125g ÷ 25cm3 = 5g/cm3
The substance has a mass of 5g per 1 cm3.
To summarize, to find the mass of one cm3 of a substance, divide the total mass of the substance by its total volume.
To determine the mass of one cm^3 of a substance, you can use the formula:
Density = Mass / Volume
Given that density is defined as mass per unit volume, rearranging the formula gives us:
Mass = Density x Volume
So, to find the mass of one cm^3 of a substance, you need to know its density. Unfortunately, the given information does not include the density of the substances in question. Without the density, it is not possible to calculate the mass of one cm^3.
If you do have the density of the substance, simply substitute the given values into the formula to find the mass of one cm^3.
