Which corresponds to a pressure of 1.23 atm? 8.73 mmhg 9.23 mmhg 125 mmhg 935 mmhg

 The value  which  corresponds to  pressure  of 1.23  atm    is 935  mm hg

 calculation

convert  1.23 atm  to  mmhg

that is   1 atm = 760   mm hg

            1.23 atm =?    mm hg

 by cross  multiplication

={( 1.23 atm  x 760  mm hg) / 1 atm} =935 mm hg

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
