What is the mass of 1.00 mol of sodium hydrogen carbonate?
And I obtained 72 also but that isn't right.
I left out the C = 12
That Na + H + C + 3O
23 + 1 + 12 + 3*48 = 84.
NaHCO3 = 1*23 + 1*1 + 3*16 = ?
Thanks
To determine the mass of 1.00 mol of sodium hydrogen carbonate, you will need to know the molar mass of sodium hydrogen carbonate.
The molar mass is the mass of one mole of a substance and is calculated by adding up the atomic masses of each atom in the chemical formula.
The chemical formula of sodium hydrogen carbonate is NaHCO3, which consists of one sodium atom (Na), one hydrogen atom (H), one carbon atom (C), and three oxygen atoms (O).
Step 1: Find the atomic mass of each element.
The atomic mass of sodium (Na) is 22.99 g/mol.
The atomic mass of hydrogen (H) is 1.01 g/mol.
The atomic mass of carbon (C) is 12.01 g/mol.
The atomic mass of oxygen (O) is 16.00 g/mol.
Step 2: Calculate the molar mass.
Multiply the atomic mass of each individual element by the number of atoms of that element in the chemical formula, then add them together.
Molar mass of NaHCO3 = (1 x Na) + (1 x H) + (1 x C) + (3 x O)
= (1 x 22.99 g/mol) + (1 x 1.01 g/mol) + (1 x 12.01 g/mol) + (3 x 16.00 g/mol)
= 22.99 g/mol + 1.01 g/mol + 12.01 g/mol + 48.00 g/mol
= 84.01 g/mol
Therefore, the molar mass of sodium hydrogen carbonate (NaHCO3) is 84.01 g/mol.
Step 3: Calculate the mass of 1.00 mol.
To find the mass of 1.00 mol of sodium hydrogen carbonate, simply multiply the molar mass by the number of moles.
Mass = Molar mass x Number of moles
= 84.01 g/mol x 1.00 mol
= 84.01 g
Hence, the mass of 1.00 mol of sodium hydrogen carbonate is 84.01 grams.
