Question

‘Mole concept can be used to calculate the relative molecular or atomic mass as well as number of particles of any substance.’ Evaluate the given statement with two relevant examples.​

Answer 1

Answer:

To find the relative formula mass (M r) of a compound, you add together the relative atomic mass values (A r values) for all the atoms in its formula. Find the M r of carbon monoxide, CO. Find the M r of sodium oxide, Na 2O. The relative formula mass of a substance, shown in grams, is called one mole of that substance.
