The height of a column of mercury in a closed-end manometer is 13.2 cm. What is the pressure of the gas in torr

AlladinOne [14]

Answer:

$P_{gas}=131.96torr$

Explanation:

Helo,

In this case, the pressure must be computed as follows:

$P_{gas}=gh\rho _{Hg}$

Which is using the density of mercury (13.6 g/mL) and its height, thus, we obtain (using the proper units):

$P_{gas}=9.8\frac{m}{s^2}*(13.2cm *\frac{1m}{100cm} )*(13.6\frac{g}{cm^3}*\frac{1kg}{1000g}*\frac{1x10^6cm^3}{1m^3} )\\\\P_{gas}=17592.96Pa*\frac{760torr}{101325Pa} \\\\P_{gas}=131.96torr$

Best regards.
