X=percentage of Cl-35
(1-x)=percentage of Cl-35
35(x)+37(1-x)=35.454
35x+37-37x=35.454
-2x=35.454-37
-2x=-1.546
x=-1.546/(-2)
x=0.773
0.773=77.3/100=77.3%
(1-x)=1-0.773=0.227
0.227=22.7/100=22.7%
answer: the percentages are: 77.3% of Cl-35 and 22.7% of Cl-37.
Explanation:
A gas has a temperature of 273.15 K and a pressure of 101.325 kPa. It can be concluded that this gas has reached standard temperature and pressure.
Standard temperature is zero degree celcius which corresponds to 273.15 degree kelvin.
Standard pressure is 760 mmHg which corresponds to 101.325 kPa.
