Use data given in the following table to calculate the molar mass of naturaly occuring argon isotopes:
`{:("Isotope",,"Isotopic molar mass",,"Abundance"),(.^(36)Ar,,35.96755 g mol^(-1),,0.337%),(.^(38)Ar,,37.96272 g mol^(-1),,0.063%),(.^(40)Ar,,39.9624 g mol^(-1),,99.600%):}`

Text Solution

Verified by Experts

Average atomic mass of argaon:
`=(35.96755 xx 0.337 + 37.96272 xx 0.063 + 39.9624 xx 99.60)/100`
`=39.948 mol^(-1)`
