Amixture of he and ne at a total pressure of 0.95 atm is found to contain 0.32 mol of he and 0.56 mol of ne. the partial pressure of ne is atm.
(a) 1.7
(b) 1.5
(c) 0.60
(d) 0.35
(e) 1.0

Partial pressure of Ne is 0.61 atm

Explanation:

Let's assume mixture of He and Ne behaves ideally.

Then, according to Dalton's law for partial pressure in a mixture of gas-

Where is partial pressure of a gas in mixture, is mole fraction of a gas in mixture and is total pressure of mixture.

Here, = (number of moles of Ne)/(Total number of moles in mixture)

So, =

So,   =

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong
