Compressed O2 is 2.2.
Chemical name for CaSO4 is calcium sulphate. It has 4 oxygen atoms in 1 molecule. So it has 12 oxygen atoms in 3 molecules.
If 3 grams of magnesium are used to form 4 grams of magnesium oxide, then 1 gram of oxygen is used in the reaction. This means 1 gram of oxygen remains unused.
Pyrophosphate has the chemical formula (P2O7)-4. It is a class of chemical anions that were originally formed from heating (pyro) phosphates. They are formed by esterification of two phosphates (linking them with one of the phosphate oxygen atoms).
C3H8 (butane) + 5 O2 (oxygen) --> 3 CO2 (carbon dioxide) + 4 H2O (water)
in every sample of carbon monoxide ,the mass ratio of carbon to oxygen is 3:4
A fourth of the class are boys, which can be expressed as a fraction as 1/4. Since the class is made up of only boys and girls, and a fourth of the class are boys, the remaining part of the class must be girls. To find the fraction of the class that are girls, you can subtract 1/4 from 1. 1 - 1/4 = 3/4 So, 3/4 of the class are girls.

The mole ratio of aluminum to oxygen in aluminum oxide (Al2O3) is 4:3, which means for every 4 moles of aluminum, there are 3 moles of oxygen.
It has 4 oxygen atoms.
A material in Class 4 Division 3, more properly called Division 4.3, is a Dangerous When Wet material.
The mass ratio of carbon to oxygen in CO2 is 3:4. This means that there are 3 parts carbon for every 4 parts oxygen in a molecule of carbon dioxide.
Class 4 division 3 (more properly called Division 4.3) is a Dangerous When Wet Material.
