Calculate the percentage by mass for Carbon in C2H2
% mass C = (2*atomic mass C/molar mass C2H2)*100 =
Oh, Carbon in C2H2? That's like a dynamic duo! Let's calculate the percentage by mass for Carbon in C2H2.
First, let's find out the molar mass of C2H2. Carbon has a molar mass of 12.01 grams per mole, and there are two carbons in C2H2, so that's 12.01 x 2 = 24.02 grams per mole.
Hydrogen has a molar mass of 1.01 grams per mole, and there are two hydrogens in C2H2, so that's 1.01 x 2 = 2.02 grams per mole.
Adding those up, we get a total molar mass of 24.02 + 2.02 = 26.04 grams per mole.
Now let's find the percentage by mass for Carbon. Carbon's molar mass is 12.01 grams per mole, so:
(12.01 grams per mole / 26.04 grams per mole) x 100% = 46.14% by mass for Carbon in C2H2.
So, Carbon makes up about 46.14% of the mass in C2H2. That's quite a substantial chunk, wouldn't you say?
To calculate the percentage by mass for carbon in C2H2 (acetylene), follow these steps:
Step 1: Find the molar mass of C2H2.
The molar mass of carbon (C) is 12.01 g/mol.
The molar mass of hydrogen (H) is 1.01 g/mol.
So, the molar mass of C2H2 is:
(2 × molar mass of C) + (2 × molar mass of H)
= (2 × 12.01 g/mol) + (2 × 1.01 g/mol)
= 24.02 g/mol + 2.02 g/mol
= 26.04 g/mol
Step 2: Calculate the mass of carbon in C2H2.
Since there are 2 carbon atoms in C2H2, multiply the molar mass of carbon by 2:
mass of carbon = (2 × molar mass of C)
= (2 × 12.01 g/mol)
= 24.02 g
Step 3: Calculate the percentage by mass of carbon.
Finally, divide the mass of carbon by the molar mass of C2H2 and multiply by 100 to get the percentage:
percentage by mass of carbon = (mass of carbon / molar mass of C2H2) × 100
= (24.02 g / 26.04 g/mol) × 100
= 92.28 %
Therefore, the percentage by mass of carbon in C2H2 is approximately 92.28%.
To calculate the percentage by mass for Carbon in C2H2 (ethylene), we need to find the molar mass of Carbon and the molar mass of the entire compound.
Step 1: Find the molar mass of Carbon (C)
The atomic mass of Carbon (C) is approximately 12.01 grams/mole.
Step 2: Find the molar mass of C2H2
Multiply the molar mass of Carbon by the number of Carbon atoms in C2H2, which is 2.
Molar mass of C2H2 = 2 * 12.01 = 24.02 grams/mole.
Step 3: Calculate the percentage by mass
To calculate the percentage by mass, we need to divide the molar mass of Carbon by the molar mass of C2H2 and multiply by 100.
Percentage by mass of Carbon in C2H2 = (Molar mass of Carbon / Molar mass of C2H2) * 100
= (12.01 / 24.02) * 100
= 0.4998 * 100
= 49.98%
Therefore, Carbon constitutes approximately 49.98% of the total mass of C2H2.
