One molecule of P2O3 = 1 mole. Go to the Periodic Table P = 30gm x 2 = 60 gm. O= 16 gm x 3 = 48 mg. Total is 60 + 48 = 108 gm is the weight of one molecule which is also the number of grams in 1 mole (remember 1 mol = 1 mole). So since you have 37.9 grams divide this by 108 and you have .35 moles.

To find the number of moles of Fe in Fe2O3, first calculate the molar mass of Fe2O3 and O. Then, determine the number of moles of O in the sample. Finally, you can use the stoichiometry of Fe2O3 to find the moles of Fe present. Alternatively, if you know the molar mass of just Fe, you can calculate the moles of Fe by dividing the mass of Fe in the sample by its molar mass.
It can be sensibly answered if you base it on the ingredient. In this case, butter. 100g of butter will come out to 105.75 ml, or 7.05 tablespoons.
16 grams of oxygen how many moles is 0,5 moles.

1 mol = 118.94 1 mol / 118.94 = 1.70 / x G = 202.10g
To calculate the number of moles of carbon in a 100g sample, you need to know the molar mass of carbon. The molar mass of carbon is 12 g/mol. Therefore, in a 100g sample, there would be 100g / 12 g/mol = 8.33 moles of carbon.
the atomic mass of gallium is approximately 69.72 g/mol therefore the mass of 100 grams of gallium would be 100g divided by 69.72g/mol which gives us approximately 1.43 moles

The chemical formula for dihydrogen phosphate ion is H2PO4-
Assuming you are talking about pure sulfer. Atomic weight of Sulfer is : 32.07g/mol 100g / 32.07 g/mol = 3.06 mol (rounded to nearest 2 decimal place) 1 mol = 6.022 141 79 × 1023 atoms. 3.06 X 6.022 141 79 × 1023 = 1.82 X 10^24 atoms
There are 10 100g weights in 1 kg.
The classical name for H2PO4 is dihydrogen phosphate.
The compound name of H2PO4 is dihydrogen phosphate.
