If 1.0 gram of matter was converted to energy, how much energy would be formed? a. 9.0 x 10-13 joules
b. 9.0 x 1013 joules
c. 3.0 x 1013 joules
d. 3.0 x 108 joules

Answer : The correct option is, (B)

Explanation : Given,

Mass of matter = 1.0 g = 0.001 g

Conversion : 1 Kg = 1000 g

Formula used :

where,

E = energy of the matter = ?

m = mass of the matter = 1.0 g

c = speed of matter =

Now put all the given values in this formula, we get :

Therefore, the energy of the matter will be,

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
