Express your answer to three significant figures. What is the total pressure in the reaction vessel after the reaction? Express your answer to three significant figures.

###### Problem

Chlorine gas reacts with fluorine gas to form chlorine trifluoride.

Cl2 (g) + 3F2 (g) → 2 ClF3 (g)

A 2.00 L reaction vessel, initially at 298 K, contains chlorine gas at a partial pressure of 337 mmHg and fluorine gas at a partial pressure of 855 mmHg.

What is the pressure of ClF3 in the reaction vessel after the reaction? Express your answer to three significant figures.

What is the total pressure in the reaction vessel after the reaction? Express your answer to three significant figures.

###### Solution

First, we have to consider that for us to be able to solve using the reaction, we would need mole values. HOwever, we are only given partial pressures and other parameters. So we would use the ideal gas equation to solve for the moles of each gas.
