The average flowrate of hydrochloric acid solution from a plant is 11,900 Lt/hr. The density is the same as that of water (1kg/Lt). The concentration of HCl in the solution is 0.015gmol/Lt.
Calculate the following:
(i) Flowrate in gallons per minute
(ii) Mass flowrate in lbm / hr
(iii) The number of gram mol of HCl flowing per minute
(iv) The mass fraction of HCl in the solution
(v) The number of lb mols of HCl in 1m3 of solution

See explanation.

Explanation:

Hello,

Here, considering the given flowrate, we perform the following units conversions for each case:

(i)

(ii)

(iii)

(iv) We find the kg of HCl per kg of acid solution:

(v)

Best regards.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
