How do you find molar mass formula?
The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.

What is the molar mass of SO4 3?
Answer and Explanation: The molar mass of Al2 (SO4)3 is 342.14 g/mole. Two aluminum atoms: 2(26.98 g/mole) = 53.96 g/mole.
What is the mole of SO4?
The answer is 0.010409878558357. We assume you are converting between moles SO4 and gram. You can view more details on each measurement unit: molecular weight of SO4 or grams The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles SO4, or 96.0626 grams.
What is the equivalent mass of SO4?
The sulfate radical (SO4) has formula weight 96.0636 and always has valence 2 in compounds, so its equivalent weight is 48.0318.
How do you find molar mass given moles and grams?
Worked Example: molar mass = mass ÷ moles (M=m/n)
- Extract the data from the question: mass = m = 29.79 g.
- Check the data for consistency: Is the mass of in grams (g)?
- Write the equation: molar mass = mass ÷ moles.
- Substitute the values into the equation and solve for molar mass:
What is the formula for finding molar mass?
Empirical formula weight = (1 x 12.01g/mol) + (2 x 1.01g/mol) + (1 x 16.00g/mol) = 30.02g/mol. Divide the molar mass for the molecular formula by the empirical formula mass.
How do you calculate molar mass?
The best way to calculate molar mass of a compound is by counting the number of atoms of a type present in it and by multiplying the number with the molecular mass of that atom . Just do the same for the other atoms present in the compound .
What is the Lewis structure of SO4?
Viewing Notes: The Lewis structure for SO42- is requires you to place more than 8 valence electrons on Sulfur (S). You might think you’ve got the correct Lewis structure for SO4 at first. Remember, Sulfur is in Period 3 and can hold more than 8 valence electrons.
How do you calculate mole?
You calculate the number of moles by dividing the mass of substance by the substance’s atomic or molecular weight. You then find the mole fraction by dividing the moles of one substance in a mixture by the total number of moles of all substances in the mixture.
