The idea is to divide the mass by the volume.
Density = Mass/Volume = 600/30 = 20 grams per ml.
Milliliters is volume and grams is mass, so you need to know mass density to solve this. For water, it has mass density of 1 gram per cubic centimeter which is the same as 1 gram per millitre of volume. So for water only, 20 ml = 20 grams.
The volume of the little cube is 23 = 8 cubic inches so the density of the material is 8/20 = 0.4 grams per cubic inch.The volume of the large cube is 83 = 512 cubic inches, so the mass (not the weight) is 512*0.4 = 128 grams.
20% of 2000 grams= 20% * 2000= 0.2 * 2000= 400 grams
Benzene is more dense than ethanol. This can be determined by calculating the density of each liquid using the formula density = mass/volume. In this case, benzene's density is higher than ethanol's because for the same volume, benzene has a higher mass.
The volume of 300 g of benzene can be calculated by dividing the mass by the density. In this case, 300 g / 0.88 g/mL = 341.35 mL. Therefore, the volume of 300 g of benzene is 341.35 mL.
The mass of 40 grams is 40 grams and the volume of 20mL is, wait for it, ... 20 mL!
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
25 grams is denser than 20 grams because density is a measure of how much mass is contained in a given volume. Since both masses occupy the same volume, the one with more mass (25 grams) will have a higher density.
To calculate the mass of benzene, use the formula: mass = volume x density. You need to know the volume of 0.1900 L of benzene at 15°C, which can be calculated using the ideal gas law or the formula for density (density = mass/volume). Once you have the volume, multiply it by the density to find the mass.
It is: 20/5 = 4 grams per cm3
Density is calculated by dividing the mass of an object by its volume. In this case, the density would be 100 grams / 5 grams = 20 grams per cubic gram.
Benzene has a chemical formula of C6H6 This has a molar mass of 78. So one mole has a mass of 78 grams
to calculate the weight from the volume, you always multiply by the density. example: If the benzene content is 2.5%v/v, then in 100mL of gasoline, you have 2.5mL of benzene. If the density of Benzene at 15.5°C is 0.81g/mL, then 2.5 x 0.81 = 2.0%w/v.
The density of the object would be 0.2 grams per cubic centimeter (mass divided by volume).
To find the volume of 54 grams of aluminum with a density of 2.7 g/cm3, divide the mass by the density: 54 grams / 2.7 g/cm3 = 20 cm3. Therefore, the volume of 54 grams of aluminum is 20 cubic centimeters.
