What is the molar mass of CF4?
The molar mass of CF4 (carbon tetrafluoride) can be calculated by adding the atomic masses of one carbon atom and four fluorine atoms. The atomic mass of carbon is approximately 12.01 g/mol, and the atomic mass of fluorine is about 19.00 g/mol. Therefore, the molar mass of CF4 is approximately 12.01 + (4 x 19.00) = 88.01 g/mol.
What is the mass of 3.7 mol of the element carbon c?
The molar mass of carbon is approximately 12.01 g/mol. Therefore, the mass of 3.7 mol of carbon would be 3.7 mol * 12.01 g/mol = 44.37 g.
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%.
How many grams of carbon are in 1.00 mol of carbon?
moles = mass/relative atomic mass 1 = mass/12 mass = 12 x 1 = 12 grams
What is percent by mass of carbon in acetone C3H6O?
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%.

What is the percentage of carbon by mass present in isopentyl acetate?
Isopentyl acetate has a molecular formula of C7H14O2. Carbon has a molar mass of 12.01 g/mol, so the molar mass of carbon in isopentyl acetate is 7 × 12.01 g/mol = 84.07 g/mol. The molar mass of isopentyl acetate is 130.19 g/mol. Therefore, the percentage of carbon by mass in isopentyl acetate is (84.07 g/mol / 130.19 g/mol) × 100% ≈ 64.6%.
How many mol of carbon are in 35 g of aluminum acetate?
To find the moles of carbon in aluminum acetate, first calculate the molar mass of aluminum acetate (Al(CH3COO)3). The molar mass of aluminum acetate is 204.12 g/mol. The molar mass of carbon is 12 g/mol. Calculate the ratio of carbon to aluminum acetate: 12 g/mol (carbon) / 204.12 g/mol (aluminum acetate) = 0.0587 mol of carbon in 1 mol of aluminum acetate. Then, calculate the moles of carbon in 35 g of aluminum acetate: 35 g / 204.12 g/mol * 0.0587 mol = 0.01 mol of carbon.
