Answer
$0.493atm$, $0.500 bar$, $375 torr$, $5.00\times 10^4 Pa$
Work Step by Step
We can convert $375\space mm\space Hg$ in to the given units as follows:
As $760mm\space Hg=1atm$
$\implies 1mm\space Hg=\frac{1atm}{760}$
$\implies 375mm\space Hg=\frac{375}{760}atm=0.493atm$
Now, we convert it into bar
As $760mm\space Hg=1.01325bar$
$\implies 1mm\space Hg=\frac{1.01325bar}{760}$
$\implies 375mm\space Hg=\frac{375\times 1.01325}{760}bar=0.500 bar$
We convert it into torr
As $760mm\space Hg=760torr$
$\implies 1mm\space Hg=\frac{760torr}{760}$
$\implies 375mm\space Hg=\frac{375\times 760}{760}torr=375torr$
We convert it into Pascals
As $760mm\space Hg=101.325KPa$
$\implies 1mm\space Hg=\frac{101.325KPa}{760}$
$\implies 375mm\space Hg=\frac{375\times 101.325KPa}{760}\times\frac{1000Pa}{1KPa}=5.00\times 10^4Pa$
