A reaction between liquid reactants takes place at in a sealed, evacuated vessel with a measured volume of . Measurements show t
Semmy [17]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The pressure is  P  = 0.76 \ atm

Explanation:

From the question we are told that

   The mass of the carbon monoxide  is  m_c  =  17 \ g

   The temperature at which takes place  T  = 30 .0^oC =  30 + 273 =  303 K

   The volume of the sealed vessel  is  V  =  20 .0L

Generally the ideal gas law is mathematically represented as

        PV  =  nRT

Where R is the gas constant with value  R =  0.0821  \ L \ atm \ mol^{-1} K^{-1}

n is the number of moles of carbon monoxide  which is mathematically evaluated as

             n =  \frac{m_c}{M_c}

where M_c is the molar mass of carbon monoxide which is a constant with value

        M_c  =  28 \ g/mol

So     n  =  \frac{17}{28}

         n  =0.6071

Now Making P the subject we have

           P  =\frac{ 0.6071 * 0.0821 * 303}{20}

           P  = 0.76 \ atm
