What is the volume of an oxygen tank if it contains 12 moles of oxygen at 273k under 75kpa?

Explanation:

Given parameters:

Number of moles = 12moles

Temperature = 273K

Pressure = 75kPa, convert to atm:

                  1kPa = 0.00986923atm

                   75kPa = 75 x 0.00986923 = 0.74atm

Unknown:

Volume of the oxygen gas

Solution:

We simply apply the idea gas law which is :

                            PV = nRT

  Since the unknown is volume, we make it the subject of the formula:

                             V =

R is the gas constant and its value is given as 0.082

           V = = 363.01L

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
