Question

A 4.0 dm' flask containing N, at 4.0 bar was connected to a 6.0 dm3
flask containing helium at 6.0 bar, & the gases were allowed to mix
isothermally, then the total pressure of the resulting mixture will be
(A) 10.0 bar
(B) 5.2 bar
(C) 1.6 bar
(D) 5.0 bar​

Answer 1

Answer:

plz mark it branliest

Explanation:

Boyle's law

PV =constant

P(N2) V(N2) + P(He) V(He)= P(total)V(total)

4×4 + 6×6 = (PV)total

16 + 36 = P(total) × 10dm^-3

P(total)= 5.2 bar
