This is a density problem. Density = mass/volume. As long as we know two of the variables, we can solve for the missing variable. The density of acetone is 0.791g/mL at 25ºC.
Known/Given:
volume of acetone= 28.62mL
density of acetone at 25oC = 0.791g/mL
Unknown:
mass of acetone
Formula:
density = mass/volume
Solve for mass:
density x volume = mass
0.791g/mL x 28.62mL = 22.6g
To find the mass of acetone, you need to know its density. The density of acetone is 0.79 g/mL. Multiply the volume (28.62 mL) by the density to get the mass in grams. Mass = Volume x Density = 28.62 mL x 0.79 g/mL = 22.58 grams.
22.39g acetone has a density of 0.7857g/cm^3 which is the same as saying 0.7857g/mL/ Multiply for mass: 0.7857*28.50=22.39g (mL gets cancelled out)
Density of acetone = 0.791 gm/mL
(0.791 gm/mL) x (17.53 mL) = 13.866 grams
28,5 mL (volume) x 0,7925 g/cm3 (density) = 22,586 g (mass)
What is the mass in grams of 33.30 mL of acetone?
The mass is 22,72 g.
To find the mass of acetone, we need to know the density of acetone, which is 0.786 g/mL. Multiplying the volume (28.40 mL) by the density gives us the mass of acetone: 28.40 mL * 0.786 g/mL = 22.33 grams.
To find the mass of 38.86 moles of acetone, you need to multiply the number of moles by the molar mass of acetone, which is approximately 58.08 g/mol. Therefore, the mass of 38.86 moles of acetone is approximately 2261.11 grams.
To calculate the concentration of acetone in ppm (parts per million), you would first convert the mass of acetone to grams (23.2 mg = 0.0232 g). Then you would divide the mass of acetone by the total mass of the solution (0.0232 g acetone / 2000 g water) and multiply by 1,000,000 to convert to ppm. Therefore, the acetone concentration would be 11.6 ppm.
To find the percent by mass of carbon in acetone (C3H6O), calculate the molar mass of carbon in acetone by adding the molar masses of the individual atoms: (3 × atomic mass of carbon) / molar mass of acetone × 100. This will give you the percentage of carbon in acetone by mass.
The molar mass of fingernail polish remover, which is typically acetone (CH3COCH3), is approximately 58 grams per mole.
With a density of 0.7857g/cm3, you have a mass of 13.78mL.
To find the mass of 38.86 moles of acetone, you need to multiply the number of moles by the molar mass of acetone, which is approximately 58.08 g/mol. Therefore, the mass of 38.86 moles of acetone is approximately 2261.11 grams.
To find the volume of 10 grams of acetone, you use the fact that the density of acetone is 0.7857 grams per cubic centimeter. The density formula is given as mass divided by volume, or m/V. The volume is mass/density or 10/0.7857, which is equal to 12.73 cubic centimeter.
To calculate the concentration of acetone in ppm (parts per million), you would first convert the mass of acetone to grams (23.2 mg = 0.0232 g). Then you would divide the mass of acetone by the total mass of the solution (0.0232 g acetone / 2000 g water) and multiply by 1,000,000 to convert to ppm. Therefore, the acetone concentration would be 11.6 ppm.
To find the volume of a substance, you would need to know its density. The density of acetone is approximately 0.79 g/mL. Using this information, you can calculate the volume of 6.54 g of acetone by dividing the mass by the density (6.54 g / 0.79 g/mL = 8.27 mL).
To find the percent by mass of carbon in acetone (C3H6O), calculate the molar mass of carbon in acetone by adding the molar masses of the individual atoms: (3 × atomic mass of carbon) / molar mass of acetone × 100. This will give you the percentage of carbon in acetone by mass.
The density acetone is 0.79 g/cm3. So 12 cm3 has a mass of 9.48 g
Acetone (C3H6O) is composed of 63.64% carbon, 13.64% hydrogen, and 22.73% oxygen by mass.
To determine the mass of the sand, you'll need to subtract the mass of the container (14.5 grams) from the total mass of the container with sand in it. For example, if the total mass of the container with sand is 50 grams, then the mass of the sand would be 50 grams - 14.5 grams = 35.5 grams.
Grams are a measure of mass.
To calculate the percent by mass of carbon in acetone (C3H6O), first calculate the molar mass of carbon in acetone: 3(C) = 3(12.01 g/mol) = 36.03 g/mol. Then calculate the molar mass of acetone: (3(12.01 g/mol) + 6(1.01 g/mol) + 16.00 g/mol = 58.08 g/mol. Finally, divide the molar mass of carbon by the molar mass of acetone and multiply by 100 to get the percent by mass of carbon in acetone: (36.03 g/mol / 58.08 g/mol) x 100 ≈ 62.07%.
80 - 75 = 5 grams.
