Question

The mass of CO that can be mixed with 70g of dry nitrogen so that both have same partial pressure
1) 70 g
2) 25 g
3) 110 g
4) 35 g
​

Answer 1

Answer:

option 1) 70g

➠partial pressure of N2 = Partial pressure of CO

⋆ Ptotal × mole fraction of N2 = Ptotal × mole fraction of CO

mole fraction of N2 = mole fraction of CO

moles of N2 = Moles of CO

70/28 = m/28

m= 70 g
