The idea is to divide the mass by the volume.
Density = Mass/Volume = 600/30 = 20 grams per ml.
To convert 200 grams per liter to percent, you divide the grams by the total volume in milliliters (1 liter = 1000 milliliters). Thus, 200 grams per liter is equivalent to 200 grams in 1000 milliliters, or 20% (since 200 grams in 1000 mL is the same as 20 grams in 100 mL). Therefore, 200 grams per liter is 20%.
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.
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.
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.
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.
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.
Benzene has a chemical formula of C6H6 This has a molar mass of 78. So one mole has a mass of 78 grams
The density of the object would be 0.2 grams per cubic centimeter (mass divided by volume).
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 rock is 20 grams/cm3. You can calculate density by dividing the mass by the 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.
