What is the relative formula mass of ethanol?
The relative formula mass of ethanol (C2H5OH) is 46 g/mol.
Calculate the mass of 0139 moles of copper?
The molar mass of copper (Cu) is 63.55 g/mol. To calculate the mass of 0.139 moles of copper, you can use the formula: mass = moles × molar mass. Therefore, the mass of 0.139 moles of copper is 8.82 grams.
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 formula mass of copper 2 flouride?
The formula mass of copper(II) fluoride (CuF2) can be calculated by adding the atomic masses of copper and two fluorine atoms. The atomic mass of copper is approximately 63.55 g/mol, and the atomic mass of fluorine is approximately 19.00 g/mol. Therefore, the formula mass of copper(II) fluoride is (1 x 63.55) + (2 x 19.00) = 101.55 g/mol.
What is the relative formula mass of iron sulphate?
The relative formula mass of iron sulfate is 151.85 g/mol. It is calculated by adding the atomic masses of all the elements in the compound, which are iron (Fe), sulfur (S), and oxygen (O).
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 iodine?
The relative formula mass of iodine is 253.8 g/mol.
What is the relative mass between iron and copper?
Iron has a relative atomic mass of approximately 55.85 g/mol, while copper has a relative atomic mass of about 63.55 g/mol. This means that copper is heavier than iron on a per-atom basis. In terms of mass ratio, copper is roughly 1.14 times the mass of iron.
What is the relative atomic mass of CU?
Copper is a meta element. Atomic mass of it is 64.
What is the rfm of 3Cu?
The RFM (Relative Formula Mass) of 3Cu (copper atoms) is calculated by multiplying the atomic mass of copper (Cu) by the number of atoms. The atomic mass of copper is approximately 63.55 g/mol. So, the RFM of 3Cu is 3 * 63.55 = 190.65 g/mol.
Why Cu has a relative atomic mass?
Copper (Cu) has a relative atomic mass because it is an average value that considers the different isotopes of copper and their abundance in nature. The relative atomic mass provides a more accurate representation of the average mass of an atom of copper compared to using just the mass number of the most abundant isotope.
What is the relative formula mass of ethanol?
The relative formula mass of ethanol (C2H5OH) is 46 g/mol.
Calculate the mass of 0139 moles of copper?
The molar mass of copper (Cu) is 63.55 g/mol. To calculate the mass of 0.139 moles of copper, you can use the formula: mass = moles × molar mass. Therefore, the mass of 0.139 moles of copper is 8.82 grams.
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.
Using the periodic table what is the mass of 2 moles of copper?
The relative atomic mass of an element is the mass in grams of 1mole of the substance. The relative atomic mass of copper is 63.5 2x63.5 = 127g
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.
