Answer:
Total space pressure space is comma
PV equals nRT
straight P equals nRT over straight V
space space equals fraction numerator bevelled fraction numerator wt over denominator mol. space wt cross times begin display style 0.0821 end style cross times 300 end fraction over denominator 10 end fraction
equals fraction numerator 0.1 cross times 24.63 over denominator 10 end fraction
equals 0.246 space atm

Partial space pressure equals space Total space pressure cross times mole space fraction
Mole space fraction space of space Helium equals fraction numerator begin display style bevelled fraction numerator 0.4 over denominator 4 end fraction end style over denominator begin display style bevelled fraction numerator 0.4 over denominator 4 cross times begin display style bevelled fraction numerator 1.6 over denominator 32 cross times begin display style bevelled fraction numerator 1.4 over denominator 14 end fraction end style end fraction end style end fraction end style end fraction
