WHAT IS THE MASS OF 0.200 mol of C9H8O4?
To determine the mass of 0.200 mol of C9H8O4, we need to know the molar mass of C9H8O4.
First, let's calculate the molar mass of each element in C9H8O4:
Carbon (C) has a molar mass of 12.01 g/mol.
Hydrogen (H) has a molar mass of 1.01 g/mol.
Oxygen (O) has a molar mass of 16.00 g/mol.
Now, let's calculate the molar mass of C9H8O4:
C9H8O4 = (9 * 12.01 g/mol) + (8 * 1.01 g/mol) + (4 * 16.00 g/mol)
C9H8O4 = 108.09 g/mol + 8.08 g/mol + 64.00 g/mol
C9H8O4 = 180.17 g/mol
Therefore, the molar mass of C9H8O4 is 180.17 g/mol.
To find the mass of 0.200 mol of C9H8O4, we can use the formula:
Mass = Number of moles * Molar mass
Mass = 0.200 mol * 180.17 g/mol
Mass = 36.034 g
Therefore, the mass of 0.200 mol of C9H8O4 is 36.034 grams.
To find the mass of a compound, you need to determine the molar mass of that compound. In this case, you want to find the mass of 0.200 mol of C9H8O4.
To calculate the molar mass of C9H8O4, you need to calculate the sum of the atomic masses of each element in the compound. To do this, you can refer to the periodic table to find the atomic masses.
The atomic masses of carbon (C), hydrogen (H), and oxygen (O) are:
- C: 12.01 grams per mole (g/mol)
- H: 1.008 g/mol
- O: 16.00 g/mol
Now, you need to count the number of atoms of each element in the compound C9H8O4.
- C: 9 atoms
- H: 8 atoms
- O: 4 atoms
Next, you multiply the atomic masses of each element by the number of atoms present in the compound:
- C: 12.01 g/mol x 9 = 108.09 g/mol
- H: 1.008 g/mol x 8 = 8.064 g/mol
- O: 16.00 g/mol x 4 = 64.00 g/mol
Finally, you add up the masses of all the elements:
108.09 g/mol + 8.064 g/mol + 64.00 g/mol = 180.154 g/mol
Therefore, the molar mass of C9H8O4 is 180.154 g/mol.
To find the mass of 0.200 mol of C9H8O4, you can use the formula:
Mass = Molar mass x Number of moles
Mass = 180.154 g/mol x 0.200 mol = 36.031 g
Therefore, the mass of 0.200 mol of C9H8O4 is 36.031 grams.
