What is the percent by mass of carbon in aceton C3H6O?
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.
What is the percent of acetone c3h6o?
Acetone (C3H6O) is composed of 63.64% carbon, 13.64% hydrogen, and 22.73% oxygen by mass.
What is the mass in grams of 38.86 of acetone?
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.
What is the percent composition of carbon in beryllium cyanide?
To determine the percent composition of carbon in beryllium cyanide, first find the molar mass of beryllium cyanide, then calculate the molar mass contributed by carbon. Finally, divide the molar mass of carbon by the total molar mass of beryllium cyanide and multiply by 100 to get the percent composition.
What is the weight percent of carbon in CH4?
Carbon has a atomic mass of 12.So its percentage is 75%

What is acetone's percent composition by mass?
%C= 62.0% %H2= 10.4% %O2= 27.5% To find these, you divide the molar mass of the specific element in the compound divided by the molar mass of the entire compound.
What is the mass in grams of 38.86 of acetone?
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.
What is the mass percent of carbon in carbon monoxide?
The molar mass of carbon monoxide (CO) is 28.01 g/mol. The molar mass of carbon is 12.01 g/mol. To find the mass percent of carbon in CO, you divide the molar mass of carbon by the molar mass of CO and multiply by 100. (12.01 g/mol / 28.01 g/mol) x 100 = 42.9% Therefore, the mass percent of carbon in carbon monoxide is approximately 42.9%.
What is the percent composition of carbon in beryllium cyanide?
To determine the percent composition of carbon in beryllium cyanide, first find the molar mass of beryllium cyanide, then calculate the molar mass contributed by carbon. Finally, divide the molar mass of carbon by the total molar mass of beryllium cyanide and multiply by 100 to get the percent composition.
What is the percent by mass of carbon in C3H8?
Well, isn't that just a happy little question! To find the percent by mass of carbon in C3H8, you first need to calculate the molar mass of carbon in C3H8, which is 3 times the molar mass of carbon. Then, you divide the molar mass of carbon by the molar mass of C3H8 and multiply by 100 to get the percent by mass. Just remember, there are no mistakes in chemistry, only happy accidents!
What is the weight percent of carbon in CH4?
Carbon has a atomic mass of 12.So its percentage is 75%
What is the percent by mass of carbon in 44g of carbon dioxide?
The molar mass of carbon dioxide (CO2) is 44 g/mol. Carbon has a molar mass of 12 g/mol and oxygen has a molar mass of 16 g/mol. So, in 44g of CO2, there are 12g of carbon. Therefore, the percent by mass of carbon in 44g of carbon dioxide is (12g / 44g) x 100 = 27.3%.
What is the mass percent of carbon in dimethylsulfoxide?
C2H6SO:C-2 (12.01)= 24.02H-6 (1.01)= 6.06S-1 (32.06)= 32.060-1 (16.00)= 16.00---------------------------= 78.14 g%C in C2H6SO= 24.02/78.14 (total mass) --> =.30739 (*100)Answer: 30.7% Carbon in dimethylsulfoxide.
What is the mass in grams of 28.40mL of acetone?
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.
