The number of moles of oxygen in the reaction vessel is?
To calculate the number of moles of oxygen in the reaction vessel, you need to know the amount of oxygen in grams and its molar mass. Then divide the mass of oxygen by its molar mass to obtain the number of moles. The formula to calculate the number of moles is: moles = mass / molar mass.
What information do you need to predict the mass of a reactant or product in a chemical reaction?
To predict the mass of a reactant or product in a chemical reaction, you would need the balanced chemical equation for the reaction, as it provides the stoichiometric ratio between the reactants and products. Additionally, you would need the molar mass of the specific substance you are interested in. With this information, you can calculate the mass using stoichiometry and molar ratios.
What information does coefficients provide in a balanced chemical equation?
Coefficients in a balanced chemical equation provide the relative ratio of reactants and products involved in a chemical reaction. They indicate the number of molecules or moles of each substance that participate in the reaction. Coefficients help to ensure that the law of conservation of mass is satisfied by showing that the same number and types of atoms are present on both sides of the equation.
What mass in grams of ethylene oxide is needed to react with 10 g of water?
To calculate the mass of ethylene oxide needed to react with 10 g of water, you need to determine the molar ratio of water to ethylene oxide in the balanced chemical equation for the reaction. Once you have the molar ratio, you can use it to calculate the mass of ethylene oxide needed. The molar mass of ethylene oxide is 44.05 g/mol.

How do you calculate mass of pure product in stoichiometry?
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.
How do you calculate the grams of an element in a specific amount of a compound?
To calculate the grams of an element in a compound, you need to find the molar mass of the element and the compound. Then, use the formula: (mass of element/molar mass of compound) x molar mass of element. This will give you the grams of the element in the compound.
What is the molar mass of the nonelectrolyte compound if a 4.305 g sample of it is dissolved in 105 g of water?
To find the molar mass of the nonelectrolyte compound, we need to use the formula: Molar mass (mass of compound / moles of compound) First, we need to find the moles of the compound by using the formula: moles mass / molar mass Given that the mass of the compound is 4.305 g and it is dissolved in 105 g of water, we can calculate the moles of the compound. Next, we can find the molar mass of the compound by rearranging the formula: Molar mass mass / moles By plugging in the values, we can calculate the molar mass of the nonelectrolyte compound.
