Because the mass of carbon is not the same as that of oxygen.
A blood level showing 63 percent oxygen is a very low reading. It indicates that the person has some type of breathing problem or interference with blood oxygenation.
it means that 70% of what is in the air is oxegon

Oxygen is a chemical element with the symbol O and atomic number of 8. Its percentage composition in the compound NiSO4 x 7H2O is 31.3%.
44.9
molecular weight of NiSO4.7H2O is 1101.3 and it has 11 oxygens. So percentage of oxygen = (7 x 16) / 1101.3 = 112 / 1101.3 = 0.102 or 10.2%
The relative molecular weight of the compound nickel (II) sulphate heptahydrate NiSO4 7H2O is 280. 86. The total mass of oxygen in the compound is 176 g. Therefore the total percentage of oxygen to the nearest tenth is 60 percent
The formula for nickel II sulfate tetrahydrate is NiSO4 * 4H2O.
The compound NiSO4 7H2O is magnesium sulfate heptahydrate. It is a type of inorganic salt that is commonly known as Epsom salt.
This compound is call Nickel sulfate NiSO4
The formula for ferrous sulfate is FeSO4.6-7H2O. (Iron Sulfate + Water) (Iron, Sulfur, Oxygen, + Hydrogen, Oxygen) No, it does not contain carbon.
Hello, Very simply, if the molar ratio is 1:1 mole, then divide the molecular weight of the anhydrous material by the hydrated one, then multiply the result by 8.753 g. Solution: NiSO4 anhydrous molecular weight is 154.75 g/mol (anhydrous) NiSO4·7H2O molecular weight is 280.86 g/mol (heptahydrate) So: 154.75/280.86 = 0.55098 The grams quantity produced from 8.753 heptahydrate is (0.55098*8.753) = 4.823 grams anhydrous NiSO4 anhydrous Best wishes AD
1. Find the molar mass (MM) of the substances.MM FeSO4 = 151.91g+MM 7H2O = 126.11gMM FeSO4 x 7H2O = 278.02g2. Find the percent water of hydrate.Divide the mass of water by the mass of the hydrate; multiply result by 100%.126.11g278.02g x 100%Percent water of FeSO4 * 7H2O is 45.36%.Finding Molar Mass# atoms Element A x atomic mass Element A = Mass A# atoms Element B x atomic mass Element B = Mass B... etc.Add up all the mass values for the substance and you have the molar mass of the substance.
