Calculate the mass percent composition of carbon in the following carbon compound.
C_8H_13O_5N
I got 0.4729 as an answer but it's wrong. Please help me.
0.4729 is correct as a fraction, convert to 47.29% by multiplying by 100.
BTW, you go to a lot of extra trouble by typing the _ to show subscripts. The tutors on the board understand that C8H12O5N is what you mean. There is a way to write subscripts but it's too much trouble to do. For example,
C8H13O5N
To calculate the mass percent composition of carbon in a compound, you need to know the molar mass of carbon and the total molar mass of the compound.
First, let's calculate the molar mass of carbon (C). Carbon has an atomic mass of approximately 12.01 g/mol.
Next, we need to calculate the molar mass of the entire compound C8H13O5N. To do this, we need to look up the atomic masses of hydrogen (H), oxygen (O), and nitrogen (N) and then multiply them by their respective subscripts.
The atomic mass of hydrogen (H) is approximately 1.008 g/mol, oxygen (O) is approximately 16.00 g/mol, and nitrogen (N) is approximately 14.01 g/mol.
Now, let's calculate the molar mass of the compound:
Molar mass = (8 * molar mass of C) + (13 * molar mass of H) + (5 * molar mass of O) + (1 * molar mass of N)
Molar mass = (8 * 12.01 g/mol) + (13 * 1.008 g/mol) + (5 * 16.00 g/mol) + (1 * 14.01 g/mol)
After performing the calculations, you should obtain the molar mass of the compound.
Finally, to calculate the mass percent composition of carbon in the compound, divide the molar mass of carbon by the molar mass of the entire compound and multiply by 100.
Mass percent composition of carbon = (molar mass of C / molar mass of compound) * 100
By following these steps, you should be able to calculate the correct mass percent composition of carbon in the given compound C8H13O5N.
