What is the chemical formula for the compound formed between barium and bromine?
The chemical formula for the compound formed between barium and bromine is BaBr2. In this compound, barium forms a +2 cation (Ba^2+) and bromine forms a -1 anion (Br^-), resulting in the formula BaBr2.
How to find the mass of an element in a compound?
To find the mass of an element in a compound, you can use the formula: mass of element (mass of compound) x (percent composition of element in compound). This formula helps you calculate the mass of a specific element within a compound based on its percentage composition.
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.
What are the sum of atomic masses of all atoms formula for a compound called?
It is called the molar mass of that compound. In other words, the total mass of all of the elements in a compound is equal to one mole of that compound.
A sample of titanium with a mass of 1.10 g was heated and completely reacted with chlorine gas. The resulting compound had a mass of 3.54 g. What is the empirical formula of the chloride that formed?
To find the empirical formula, you first need to determine the moles of titanium and chlorine in the compound. The molar mass of titanium is 47.87 g/mol, and chlorine is 35.45 g/mol. From the given masses, you can calculate the moles of titanium and chlorine in the compound. Then, divide the moles by the smallest number of moles to get the mole ratio for the empirical formula. In this case, the empirical formula of the chloride formed is TiCl3.
What is the chemical formula for the compound formed between barium and bromine?
The chemical formula for the compound formed between barium and bromine is BaBr2. In this compound, barium forms a +2 cation (Ba^2+) and bromine forms a -1 anion (Br^-), resulting in the formula BaBr2.
The mole establishes a relationship between the?
the molecular mass of a compound and its empirical formula
How do you calculate the equivalent weight of compound?
the sum of the atomic weights for all the atoms in the formula
A compound has a mass of 16.7g 12.7g Iodine 4g Oxygen Therefore the empirical formula is I2O5 What additional information do you need to work out the molecular formula?
To determine the molecular formula, you would need the molar mass of the compound. With the molar mass, you can calculate the empirical formula mass and then determine the ratio between the empirical formula mass and the molar mass to find the molecular formula.

What is gram formula mass?
The mass of a mole of an ionic compound.
What is the formula for the percent by mass of a compound?
((mass of element)/(mass of compound))*100
What does an empirical formula show?
the empirical formula of a compound tells you the proportions of the elements in the compound. with that information you can make some inferences about the identity of the compound. for example a compound with an empirical formula CH4 tells us that for every carbon atom there are four hydrogen atoms. this means that the compound is methane because no other hydrocarbon can have these roportions (try drawing the lewis structure for C2H8, which doesnt exist. you cant!)
What information is needed to calculate the percent composition of a compound?
The formula of the compound and the Atomic Mass of its elements.
