What is the relative mass of so2?

The relative atomic mass of sulfur is 32.06 g/mol and the relative atomic mass of oxygen is 16.00 g/mol. Therefore, the relative molecular mass of SO2 (sulfur dioxide) is 32.06 + (16.00 x 2) = 64.06 g/mol.


What is the relative formula mass of iodine?

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


What is the percent by mass of sulfur in sulfur dioxide?

The molar mass of sulfur dioxide (SO2) is 64.06 g/mol. The molar mass of sulfur is 32.06 g/mol. Calculate the mass percent of sulfur in SO2 using the formula (mass of sulfur / mass of SO2) x 100%. This gives a mass percent of sulfur in SO2 as 50%.


How many moles in 37.4g of SO2?

The formula mass of the compound sulfur dioxide, SO2 is 32.1 + 2(16.0) = 64.1Amount of SO2 = mass of pure sample/molar mass = 37.4/64.1 = 0.583mol There are 0.583 moles of sulfur dioxide in a 37.4g pure sample.


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.


What is the relative formula mass of ethanol?

The relative formula mass of ethanol (C2H5OH) is 46 g/mol.

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.
