What volume of oxygen (NTP) will be required to react with 1 g of Ca?

Text Solution

Verified by Experts

As Ca combines with `O_(2)` to give CaO , from the formula of CaO,
We have
moles of Ca = moles of O (atoms)
`(wt. of Ca)/( at . wt.) = ("vol . of O atoms at NTP")/("vol . occupied by 1 mole of O atoms of NTP")`
`(1)/(40)= (vol . of O)/( 11.2)`
` :. ` vol of O = `(11.2)/( 40) = 0 . 28` litre.
