Which must be the same when comparing 1 mol of oxygen gas, o2, with 1 mol of carbon monoxide gas, co? the mass the volume the number of molecules the number of oxygen atoms

Answer : The correct option is, the number of molecules.

Explanation :

As we are given that 1 mole of oxygen gas, and 1 mole of carbon monoxide gas, (CO).

From the given options, the number of molecules must be same when comparing 1 mole of oxygen gas, and 1 mole of carbon monoxide gas, (CO) because there are 2 molecules present in both oxygen gas and carbon monoxide gas.

The mass of 1 mole of oxygen gas, is, 32 g and the mass of 1 mole of carbon monoxide gas, (CO) is, 28 g. So, the mass will not be same.

The number of oxygen atoms in 1 mole of oxygen gas, is, and the number of oxygen atoms in 1 mole of carbon monoxide gas, (CO) is, . So, the number of oxygen atoms will not be same.

The volume of 1 mole of oxygen gas, and 1 mole of carbon monoxide gas, (CO) will not be same due to the difference in the masses.

Hence, the correct option is, the number of molecules.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
