What is the density and specific gravity andof a substance that has a mass of 321 gramsand a volume of 45cc at a room temperature?

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.


What is the density if the volume of a body is 45cc and mass is 180 kg?

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.


What is 45cc equal to?

45 cc = 45 centilitres = 0.45 litres.


How do you find the percent of oxygen by mass in a compound?

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.

What is the mass percent of oxygen in the compound?

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%.


What is the percent by mass of oxygen in propanal CH3CH2CHO?

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%.


If the atomic mass of oxygen?

Oxygen is a metal element. Atomic mass of it is 16.
