the water can be made to boil at 0 deg C if pressure of surrounding is______mm of Hg

a)76

b)5 cm

c)0.1

d)4.6

PLS TEL BE IF THERE IS ANY FORMULA FOR THIS>> IF ANY <<

boiling point(in fahrenheit) = 49.161 * Ln (Pressure in inches Hg) + 44.932

Ln (Pressure in inches Hg)=32-44.932= -12.932,
(Pressure in inches Hg)=e^-12.932 =2.42*10^-6=2.42*2.54*10^-5 =6.1468*10^-5 mm Hg
