What additional information is needed to calculate the molecular formula from the percent by mass of each element in a compound?
In addition to the percent by mass of each element, you also need the molar mass of each element. This information allows you to convert the percent by mass into grams and then into moles, which is necessary to determine the empirical formula and subsequently the molecular formula of the compound.

How can one determine the molecular formula from the given molar mass and percent composition?
To determine the molecular formula from the given molar mass and percent composition, you can follow these steps: Convert the percent composition to grams for each element present in the compound. Calculate the number of moles of each element using the molar mass and the grams of each element. Divide the moles of each element by the smallest number of moles to get the mole ratio. Use the mole ratio to determine the empirical formula. Calculate the empirical formula mass and compare it to the given molar mass to find the multiplier needed to get the molecular formula.
What is the mass percent of oxygen in the compound?
To determine the mass percent of oxygen in a compound, you would calculate the mass of oxygen in the compound and then divide it by the total mass of the compound, before multiplying by 100. The formula is: (mass of oxygen in compound / total mass of compound) x 100%.
How can one determine the empirical formula from mass percent composition?
To determine the empirical formula from mass percent composition, one must convert the mass percentages of each element in a compound into moles. Then, divide the moles of each element by the smallest number of moles to find the simplest whole number ratio of elements in the compound, which represents the empirical formula.
What is the formula of percent by volume and mass?
The formula for percent by volume (% v/v) is: (Volume of solute / Volume of solution) x 100 The formula for percent by mass (% w/w) is: (Mass of solute / Mass of solution) x 100

What is the formula of the percent of volume and percent of mass?
% of volume = 100*(volume of substance that you are interested in)/(total volume) % of mass = 100*(mass of substance that you are interested in)/(total mass).
What is the percent composition of ammonium carbonate?
Ammonium carbonate has the formula (NH4)2CO3. To calculate the percent composition, you first find the molar mass of each element and then divide the molar mass of each element in the formula by the formula mass of the compound and multiply by 100 to get the percentage.

What is the mass percent of H in ammonium bicarbonate?
The molecular formula of ammonium bicarbonate is NH4HCO3. To find the mass percent of hydrogen (H) in it, we calculate the molar mass of hydrogen in the formula and divide it by the molar mass of the whole compound NH4HCO3, then multiply by 100. The mass percent of hydrogen in ammonium bicarbonate is approximately 5.9%.
What is the formula for the percent by mass of a compound?
((mass of element)/(mass of compound))*100
What information is needed to calculate the percent composition of a compound?
The formula of the compound and the Atomic Mass of its elements.

What is the percent by mass of sulfur in sulfur dioxide?
The molar mass of sulfur dioxide (SO2) is 64.06 g/mol. The molar mass of sulfur is 32.06 g/mol. Calculate the mass percent of sulfur in SO2 using the formula (mass of sulfur / mass of SO2) x 100%. This gives a mass percent of sulfur in SO2 as 50%.
