How do you find theoretical percent of water?
To find the theoretical percent of water in a compound, you need to determine the molar mass of the compound and the molar mass of water. Then, divide the molar mass of water by the molar mass of the compound and multiply by 100 to get the percentage.
How can you find the mass of any compound?
The molar mass of a compound is the sum of atomic weights of elements in the molecule.
How is the mass compound determined from the number of moles?
Multiply the number of moles times the molar mass of the compound. Moles cancel and you are left with mass in grams.For example: What is the mass of 2.47 moles of sodium chloride, NaCl?Known: The molar mass of NaCl is 58.44g/mol. (Using atomic weights in grams from the periodic table.)Solution:2.47mol NaCl x 58.44g/mol NaCl = 144g NaCl
What is he molar mass of a molecule what unit is it in?
The molar mass of a compound is the sum of the atomic weights of the contained elements.
The combustion data for an unknown compound containing carbon hydrogen and oxygen was analyzed and the empirical formula for the unknown was found to be C3H5O The molar mass of the unknown was found?
To find the molecular formula from the empirical formula (C3H5O) and molar mass, you need to calculate the molar mass of the empirical formula. Then, divide the molar mass of the unknown compound by the molar mass of the empirical formula to get a ratio. Finally, multiply the subscripts in the empirical formula (C3H5O) by this ratio to determine the molecular formula of the unknown compound.
How do you find the percent of oxygen by mass in a compound?
To find the percent of oxygen by mass in a compound, you need to know the molar mass of the compound and the molar mass of oxygen. Divide the molar mass of oxygen by the molar mass of the compound and multiply by 100 to get the percentage.
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.
How do you find theoretical percent of water?
To find the theoretical percent of water in a compound, you need to determine the molar mass of the compound and the molar mass of water. Then, divide the molar mass of water by the molar mass of the compound and multiply by 100 to get the percentage.
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.
How can you find the mass of any compound?
The molar mass of a compound is the sum of atomic weights of elements in the molecule.
What is the mass percent of hydrogen in ammonium phosphate NH4 3PO4?
To find the mass percent of hydrogen in ammonium phosphate NH4 3PO4, first calculate the total molar mass of the compound. Then, determine the molar mass contributed by hydrogen. Finally, divide the molar mass of hydrogen by the total molar mass of the compound and multiply by 100 to get the mass percent.
How to find the mass of an element in a chemical compound?
To find the mass of an element in a chemical compound, you can use the atomic mass of the element from the periodic table and the number of atoms of that element in the compound. Multiply the atomic mass by the number of atoms, and you will get the mass of that element in the compound.
What is the percentage composition of molar mass in the given compound?
The percentage composition of molar mass in a compound is the percentage of each element's mass contribution to the total molar mass of the compound.
If 60.2 grams of Hg combines completely with 24.0 grams of Br to form a compound what is the percent composition of Hg in the compound?
To find the percent composition of mercury (Hg) in the compound, you first calculate the molar mass of each element. Then, find the molar mass of the compound by adding the molar masses of Hg and Br. Divide the molar mass of Hg by the molar mass of the compound and multiply by 100 to get the percentage. In this case, the percent composition of Hg in the compound is approximately 71%.
Does the molar mass of a compound change depending on the weight of the compound?
Molar mass depend on the ,mass,type and number of atoms in molecules of compound.
How do you Find the percent composition of oxygen in each of the following compounds?
To find the percent composition of oxygen in a compound, divide the molar mass of the oxygen in the compound by the molar mass of the entire compound, then multiply by 100 to get the percentage. Repeat this calculation for each compound listed.
What is the percent by mass of oxygen in propanal CH3CH2CHO?
To find the percent by mass of oxygen in propanal (CH3CH2CHO), calculate the molar mass of oxygen (O) and the molar mass of the entire compound. Then divide the molar mass of oxygen by the molar mass of the entire compound and multiply by 100 to get the percentage. In this case, the percent by mass of oxygen in propanal is around 47.3%.
