How do you calculate the moles of an element in a compound?
Once you've found the molecular weight, you know the weight of one mole of a compound. To find the number of moles in a sample, simply weigh it and divide the weight by the molecular weight. The quotient is equal to the number of moles.
How do you find moles from grams?
You have three steps to convert mole values to grams.
- Calculate how many moles are mentioned in the question.
- Find the molar mass of the substance.
- Multiply both the values.
How do you calculate moles produced?
Determine the moles of product produced by dividing the grams of product by the grams per mole of product. You now have calculated the number of moles of every compound used in this reaction. 41.304 g of NaCl ÷ 58.243 g/mol = 0.70917 moles of NaCl.
How do you calculate the number of moles?
To find the number of moles in a sample, simply weigh it and divide the weight by the molecular weight. The quotient is equal to the number of moles. Example: How many moles are there in 300 grams of sodium bicarbonate? The molecular weight of sodium bicarbonate is 84 grams/mole.
How do you find the excess reactant?
The reactant that produces a larger amount of product is the excess reagent. To find the amount of remaining excess reactant, subtract the mass of excess reagent consumed from the total mass of excess reagent given.

How do you find the number of moles from grams?
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.

What is a excess reactant?
An excess reactant is a reactant present in an amount in excess of that required to combine with all of the limiting reactant. It follows that an excess reactant is one remaining in the reaction mixture once all the limiting reactant is consumed.

What is a excess reactant example?
Examples of Excess Reactant The amount of product formed is independent of oxygen. Thus oxygen is an excess reactant here. A combustion reaction occurs when methane gas is burned in the air, i.e. oxygen. The amount of product formed is independent of oxygen. Thus oxygen is an excess reactant here.
