1200[tex]cm^{3}[/tex] of oxygen gas are required during the burning of magnesium.
mass of oxygen=(4-2.4)= 1.6g
moles of oxygen= 1.6/ 16 =0.1
if one mole oxygen-----> 24,000[tex]cm^{3}[/tex]
0.1 mole Mg =0.5 mol oxygen = 1200[tex]cm^{3}[/tex]
Using the ideal gas law, determine the volume (in cubic meters) of gaseous oxygen by multiplying the amount of oxygen (in moles) by the temperature and the molar gas constant, then dividing the result by the pressure.
The manufacture of steel, plastics, and textiles, the brazing, welding, and cutting of steel and other metals, the creation of rocket propellant, oxygen therapy, and the life support systems in aircraft, submarines, and spacecraft are all common uses of oxygen.
