CO2 + 4H2 --> CH4 + 2H2O0.500 moles CO2 (1 mole CH4/1 mole CO2) = 0.500 moles CH40.500 moles CO2 (2 moles H2O/1 mole CO2) = 1.00 moles H2O-------------------------------------------------------------------------------------add= 1.50 moles total product====================
Stoichiometry relates moles of reactant to moles of product, so if you have the amount of reactant in the equation, you can calculate the amount of product produced.
The coefficients give the ratio of moles reactant to moles product.
Convert grams of the given reactant to moles using its molar mass. Use the mole ratio from the balanced chemical equation to convert moles of the given reactant to moles of the desired product. Convert moles of the desired product to grams using its molar mass, if needed.
To calculate the mass of a pure product in stoichiometry, you need to use the stoichiometric coefficients from the balanced chemical equation to convert the given amount of reactant into the desired product. Once you have determined the moles of the product, you can then convert moles to grams using the molar mass of the product. This will give you the mass of the pure product produced.
0,83moles glucose are burned.
8,54 mL toluene is equivalent to 0,08 moles.

Since the product, K2SO4 has twice as many potassium atoms as the reactant, KNO3, we may conclude that it takes two moles of reactant to produce one mole of product. The sulfate and nitrate ions will not be the limiting factor.
The coefficients give the ratio of moles reactant to moles product.
To determine how many moles of Na2CO3 are used, you need to know the molar mass of Na2CO3. It is 105.99 g/mol. Then, you can calculate the number of moles using the given mass: mass in grams / molar mass = moles of Na2CO3.
Moles of one substance compared to moles of the second substance. Ex. moles of reactant A compared to moles pf product F
Balanced equation. 2Fe + 3Br2 -> 2FeBr3 need limiting reactant; suspect iron 9.20 mole Fe (3 mole Br2/2 mole Fe) = 13.8 moles the stated iron moles are not nearly this much; iron limits and drives the reaction looks one to one, so................ 9.20 moles Fe (2 moles FeBr3/ 2mole Fe) = 9.20 moles FeBr3 produced
Convert grams of the given reactant to moles using its molar mass. Use the mole ratio from the balanced chemical equation to convert moles of the given reactant to moles of the desired product. Convert moles of the desired product to grams using its molar mass, if needed.
Of course 6 moles.
