In a mixture containing 8.2 g Ca, 10 mm `NaNO_(3)` , calculate the total no. of oxygen and nitrogen atoms present in amixture. Report your answer to their nearest whole number ratio.

Answer

`2`

Explanation

`{:(" ""N atoms"" ""O atoms"),(8.2g Ca" "X" "X),(10 mm "of" NaNO_(3)" "1xx10^(-2)xxN_(0)" "3xx10^(-2)N_(0)),("No/6 molecules" NO_(2)" "1/6N_(0)" "2/6N_(0)),(" "………………." "...............),("Total" " "[0.01+0.167]N_(0)" "[0.03+0.333]N_(0)):}`
`[0.177]N_(0)" "[0.363]N_(0)`
of N atoms`" "` of O atoms
`("N atoms")/("O atoms")=(0.396N_(0))/(0.177N_(0))`
`=2`
