What is the relative formula mass of iodine?

The relative formula mass of iodine is 253.8 g/mol.


What is the relative formula mass of copper?

The relative atomic mass of copper is approximately 63.55. To calculate the relative formula mass of copper, you sum the atomic masses of its atoms, which in this case would just be the atomic mass of copper. Therefore, the relative formula mass of copper would be 63.55.


How do you calculate the density of an ethanol-water mixture?

To calculate the density of an ethanol-water mixture, you would use the formula: Density (mass of ethanol mass of water) / (volume of ethanol volume of water) You would need to know the masses and volumes of both ethanol and water in the mixture. Then, you can plug these values into the formula to find the density of the mixture.


What is the relative formula mass of nitrate?

The chemical formula is (NO3)-; the mass is 62 g.


What are the relative formula masses of hydrogen molecules?

The relative formula mass of a hydrogen molecule (H2) is calculated by adding the atomic masses of the two hydrogen atoms. Each hydrogen atom has an atomic mass of approximately 1, so the relative formula mass of a hydrogen molecule is 2.


What is the relative formula mass of lead oxide?

The relative formula mass of lead oxide (PbO) is calculated by adding the atomic masses of the elements in the formula. The atomic mass of lead (Pb) is 207.2 g/mol, and the atomic mass of oxygen (O) is 16.0 g/mol. Therefore, the relative formula mass of lead oxide is 207.2 + 16.0 = 223.2 g/mol.


What is the mass of 0.5623 moles of ethanol ch3ch2oh?

To calculate the mass of 0.5623 moles of ethanol (C2H5OH), you need to use the molecular weight of ethanol, which is approximately 46.07 g/mol. Multiply the number of moles by the molecular weight to get the mass: 0.5623 moles x 46.07 g/mol ≈ 25.89 grams. Therefore, the mass of 0.5623 moles of ethanol is approximately 25.89 grams.


What is the formula mass of hydrogen?

The relative formula mass of a molecule of hydrgoen is two (2 x 1).


What is the condensed formula for ethanol?

The chemical formula of ethanol is C2H5OH.


What is the relative formula mass for MgCO3?

The relative formula mass of MgCO3 is 84.3 g/mol. This is calculated by adding the atomic masses of magnesium (24.3 g/mol), carbon (12.0 g/mol), and three oxygen atoms (16.0 g/mol each) together.


How do you find the total volume of ethanol if the total mass is 60.345?

Divide by the density of ethanol.Assuming that it is a total mass of 60.354 grams, and the density of ethanol is 0.789 grams per cm3 (or grams per mL), then the volume of that much ethanol is:60.354 grams ÷ 0.789 grams/mL = 76.494 mL


HOW DO I CALCULATE THE PERCENTAGE BY MASS OF ETHANOL IN A MIXTURE OF ETHANOL AND WATER?

Divide the mass of the ethanol by the sum of the mass of the ethanol + that of the water and multiply by 100. Mass ethanol/(Mass ethanol + mass H2O) (x100)
