How Does Mercury's Density Affect Column Pressure in hPa?

[teng125]

What is the pressure of a 10 cm high column of mercury
(ρ = 13,6 g/cm^3) in hPa?

i know that the formula is Pressure=pgh so i subs in 13.6g/cm^3 (9.81m/s^2) (10cm).
may i know what is the g in 13.6g/cm^3 belongs to??

is it equals to 9.81m/s^2??
and also what is hPa??i know Pa is pascal but don't know h

anybody pls help
thanx

hPa is 10^2, so 100 times a Pa. And assume g is 9.81ms^-2. I'm not sure what you mean "what the 'g' in 13.6g/cm^3 belongs to" question, but g is not a variable in there, it's an indication that the density is in grams per centimeter cubed, so keep the units in centimeters and grams, and the answer should be ok.
