At 45.2 L cylinder containing C2H2F4 at a pressure of 3.00 atm is connected by the valve to 4060 mL cylinder containing N2H4 at
puteri [66]

The partial pressure of the N2H4 gas  is 1.50 atm.

<h3>Dalton's law of partial pressure</h3>

From the Dalton's law of partial pressure, the total pressure of a mixture of gases is the sum of the individual partial pressures of all the gases present in the mixture.

We have the following;

C2H2F4  =  3.00 atm

N2H4 = c

Total pressure = 3.00 atm + 1.50 atm = 4.50 atm

Hence, the partial pressure of the N2H4  is N2H4.
