What is the percentage of nitrogen in n2o4?
The percentage of nitrogen in N2O4 is 63.6%. This is determined by dividing the molar mass of nitrogen in N2O4 by the molar mass of the compound and then multiplying by 100.
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 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.
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 is the molecular formula of a compound with the empirical formula NH2Cl and molar mass of 51.5g mol?
The empirical formula NH2Cl has a molar mass of 51.5 g/mol, so the molecular formula can be determined by finding the ratio of the molar mass of the molecular formula to the molar mass of the empirical formula. The molecular formula of the compound is therefore NH2Cl2.
How is a mass of a compound determined the number of moles?
The molar mass of a compound is equal to 1 mol.
How is the mass of a compund determined from the number of moles?
1 mol is equivalent to the molar mass of a compound, in grams.
What is the percentage of nitrogen in n2o4?
The percentage of nitrogen in N2O4 is 63.6%. This is determined by dividing the molar mass of nitrogen in N2O4 by the molar mass of the compound and then multiplying by 100.
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 molecular formula of the compound CH2 with molar mass = 42.0?
The molecular formula of a compound can not be determined solely based on its molar mass. In this case, without additional information, it is not possible to determine the molecular formula of the compound CH2.
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.
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.
Does the mass of each element in a compound depend on the amount of compound?
Yes, because the mass of each element in a compound depends on the mass of the compound.
What is the molecular formula of a compound with the empirical formula NH2Cl and molar mass of 51.5g mol?
The empirical formula NH2Cl has a molar mass of 51.5 g/mol, so the molecular formula can be determined by finding the ratio of the molar mass of the molecular formula to the molar mass of the empirical formula. The molecular formula of the compound is therefore NH2Cl2.
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 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
How is molar mass of an element determined?
the Atomic Mass in g/ml is the molar mass of the element
