Room temperature:   294.0 K

Barometric pressure:   763.0 mmHg

Vapor of water:   18.6 mmHg

Volume of O2 collected:   65.50 mL

Density of H2O2:   1.01 g/mL

% Composition H2O2:   3.02 %

Volume of H2O2 used:   5.00 mL

Letter of the unknown solution of H2O2:   C

Volume of O2 collected for the unknown:   53.00 mL

Calculate the corrected barometric pressure.

Expert Answer

Step 1

Given that,

Barometric pressure = 763mmHg

Vapour pressure = 18.6 mmHg

Step 2

Now you calculate the correct...

corrected barometric pressure=barometric presssure-vopour pressure
763 mmHg-18.6 mmHg
=744.4 mmHg
