What type of liquid is mercury

Elemental mercury is the most common form. It is a metallic, silvery liquid ( also referred to as quicksilver) that is processed from an ore called cinnabar. It readily breaks into droplets and easily vaporizes at room temperature into an odorless, colorless vapor that can easily be inhaled.

Explanation:

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

the answer would be c
