density = mass divided by volume density = 20/10 = 2 g/cm3
Density = mass/volume = 20g/8cm3 = 2.5 grams per cm3
Denisty = Mass/Volume = 20/4 = 5 g/cm3
density = mass ÷ volume= 20 g ÷ 12 cm3≈ 1.67 g/cm3
2 g/cm3. This can be done by using the formula for density (mass/volume) and conversion 1mL=1cm3 The density of that liquid is 2.
To find the density of an object, you need to divide its mass by its volume. In this case, the mass is 20g and the volume is 10cm3. Therefore, the density would be 20g divided by 10cm3, which equals 2g/cm3.
density = mass divided by volume density = 20/10 = 2 g/cm3
Density = mass/volume = 20g/8cm3 = 2.5 grams per cm3
The density of the mineral sample is 1.67 g/cm3. This is calculated by dividing the mass (20g) by the volume (12cm3).
The density of the object is 0.25 g/cm3. This is calculated by dividing the mass (20g) by the volume (80cm3).
The density of the object is calculated by dividing the mass by the volume. In this case, the density would be 2 g/ml.
Denisty = Mass/Volume = 20/4 = 5 g/cm3
The density is calculated by dividing the mass by the volume. In this case, density = mass/volume = 20g / 5 cm^3 = 4 g/cm^3.
density = mass ÷ volume= 20 g ÷ 12 cm3≈ 1.67 g/cm3
The volume of the sample whose mass is 20 g and density is 4 g/ml is 5 milliliters.
You cannot directly associate weight and volume. You firstly need to know the shape and other dimensions in order to find the volume. Then you need to apply the density of the material, i.e. what it weighs per volume.
To find the number of water molecules in 20g of CuSO4.5H2O, we first need to calculate the molar mass of CuSO4.5H2O. The molar mass of CuSO4.5H2O is 249.68 g/mol. Then we can use the molar mass of CuSO4.5H2O to find the number of moles in 20g. Finally, as there are 5 water molecules in one formula unit of CuSO4.5H2O, we can calculate the number of water molecules corresponding to 20g of CuSO4.5H2O.
