Mass defect for oxygen-16 = 0. 13261 amu, in the kilograms the mass defect equals to 2.20 × 10⁻²⁸ kg.

<h3>What is mass defect?</h3>

Mass defect is the difference between the mass of of an whole atom and the combined mass of its individual particles present in that atom.

We know that, 1 amu = 1.6 × 10⁻²⁷ kg

Given that, mass defect for oxygen-16 = 0.13261 amu

To calculate this defect in terms of kilograms, we have to convert into kg unit as:

0.13261 amu = 0.13261 amu × 1.6 × 10⁻²⁷ kg/amu

0.13261 amu = 2.20 × 10⁻²⁸ kg

Hence option (2) is correct.

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

4 C3H6 + 6 NO --&gt; 4 C3H3N + 6 H2O + N2
emmasim [6.3K]

4 moles

Explanation:

Given parameters:

number of moles of reacting NO = 24moles

Equation of the reaction:

    4C₃H₆     +     6NO    ⇒     4C₃H₃N   +  H₂O    +     N₂

Solution:

The moles is synonymous the quantity of matter that contains the avogadro's number of particles.

To solve this problem, we must ensure that the given equation is balanced by simply inspecting.

 The equation is balanced by inspection.

From the balanced equation;

          6 moles of NO reacted to produce 1 mole of nitrogen gas

        24 moles of NO will therefore produce    \frac{24}{6} = 4 moles
