Expert Answer:

The space reaction space equation space is colon
Zn space space space plus space space space 2 HCl space space rightwards arrow space space ZnCl subscript 2 space space space plus space straight H subscript 2
65 space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space 22.4 space straight L

65 space gm space of space zinc space produce space 22.4 space litres space of space hydrogen space at space STP

20 space gm space of space zinc space will space produce space space space fraction numerator 22.4 cross times 20 over denominator 65 end fraction
space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 6.89 space litres space of space hydrogen space at space STP

space space space PV over straight T equals fraction numerator straight P apostrophe straight V apostrophe over denominator straight T apostrophe end fraction

therefore space Volume space at space 20 space to the power of 0 straight C space and space 750 space mm space

straight T equals 273 plus 20 space equals space 293 space straight K

fraction numerator 750 cross times straight V over denominator 293 end fraction equals fraction numerator 760 cross times 6.89 over denominator 273 end fraction

space space space space space straight V space space space equals space space space fraction numerator 760 cross times 6.89 cross times 293 over denominator 273 cross times 750 end fraction


space space space space space straight V space equals space space 7.49 space litres space of space straight H subscript 2
