The mass of 4,5 cm3 of oxygen at 20 0C is 6,4305 mg.
about 1000 k/ph
The density of the substance is calculated by dividing the mass (321g) by the volume (45cc), which gives 7.13 g/cc. The specific gravity is the ratio of the density of the substance to the density of water at 4 degrees Celsius, which is 1 g/cc. Therefore, the specific gravity of the substance is 7.13.
Density = Mass/Volume = 180/45 = 4 kg per cc. That is very dense material - more than 180 times as dense as the densest element on earth - Osmium.
45 cc = 45 centilitres = 0.45 litres.
To find the percent of oxygen by mass in a compound, you need to know the molar mass of the compound and the molar mass of oxygen. Divide the molar mass of oxygen by the molar mass of the compound and multiply by 100 to get the percentage.
The density of the substance is calculated by dividing its mass (321 grams) by its volume (45 cc), which results in 7.13 g/cc. The specific gravity is the ratio of the density of the substance to the density of water at 4 degrees Celsius, which is 1 g/cc, so the specific gravity would be 7.13.
The percent by mass of oxygen in N2O4 is 69,56 %.

Oxygen is a non meta element. Atomic mass of it is 16.
To determine the mass percent of oxygen in a compound, you would calculate the mass of oxygen in the compound and then divide it by the total mass of the compound, before multiplying by 100. The formula is: (mass of oxygen in compound / total mass of compound) x 100%.
To find the percent by mass of oxygen in propanal (CH3CH2CHO), calculate the molar mass of oxygen (O) and the molar mass of the entire compound. Then divide the molar mass of oxygen by the molar mass of the entire compound and multiply by 100 to get the percentage. In this case, the percent by mass of oxygen in propanal is around 47.3%.
Oxygen is a metal element. Atomic mass of it is 16.
