Question

The vapor pressure of water at 80°C is 0.4675 atm. Calculate the vapor pressure in kPa. Be sure your answer has the right number of significant digits.

Answer 1

$0.4675\ atm= 0.4675\times (1\ atm)$

$0.4675\ atm= 0.4675\times (1.01325\ bar)$

$0.4675\ atm\approx \boldsymbol{0.4737\ bar}$

And,

$0.4675\ atm=0.4737\times (1\ bar)$

$0.4675\ atm=0.4737\times (10^5\ Pa)$

$0.4675\ atm=\boldsymbol{47.37\ kPa}$

=47.37 kPa
