what is the molar mass for C2H5OH in grams
To calculate the molar mass of a compound, you need to find the atomic masses of all the elements present in the compound and then sum them up.
Step 1: Find the atomic masses
The atomic mass of carbon (C) is approximately 12.01 grams/mol.
The atomic mass of hydrogen (H) is approximately 1.01 grams/mol.
The atomic mass of oxygen (O) is approximately 16.00 grams/mol.
Step 2: Determine the number of atoms of each element
In C2H5OH, there are 2 carbon atoms (C), 6 hydrogen atoms (H), and 1 oxygen atom (O).
Step 3: Calculate the molar mass
Now, calculate the molar mass by multiplying the number of atoms of each element by their respective atomic masses and then summing them up:
Molar mass = (2 * atomic mass of C) + (6 * atomic mass of H) + (1 * atomic mass of O)
Molar mass = (2 * 12.01 g/mol) + (6 * 1.01 g/mol) + (1 * 16.00 g/mol)
Molar mass = 24.02 g/mol + 6.06 g/mol + 16.00 g/mol
Molar mass = 46.08 g/mol
Therefore, the molar mass of C2H5OH (ethanol) is approximately 46.08 grams/mol.
