hello there welcome to study pool!


we can use following equation to solve the problem

V=(3RT/M)^1/2


v-mean speed

R-gas constant

T-temperture

M-molar mass

at same T and R

v=K(1/M)^1/2


443=K(1/32)^1/2-------(1)

v=K(1/44)^1/2------------(2)

(1)/(2)

443/v=(44/32)^1/2

443/1.72=v

v=257.56m/s
