2.3 grams P (1mole P/30.97 grams) = 0.07427 moles Phosphorous 0.07427 moles P * 6.022 X 10^23 = 4.5 X 10^22 atoms of P in 2.3 grams P 4.5 X 10^22/6.022 X10^23 = 0.07427 moles of atoms in 2.3 grams of phosphorous
Moles=given wt./molecular weight 1.25=given wt./70 given wt.=70*1.25=87.5 gm

There are 1000 grams in one kilogram. Therefore, 31 kilograms is equal to 31 x 1000 = 31000 grams.
To find the number of moles in 31 grams of CH2O, we divide the mass by the molar mass of CH2O (30.03 g/mol). This gives us approximately 1.03 moles of CH2O. Since there are two hydrogen atoms in each molecule of CH2O, we multiply the number of moles by Avogadro's number (6.02 x 10^23) and by 2 to find about 1.24 x 10^24 hydrogen atoms.
