Explanation:

An atom is the smallest indivisible particle of an element. It is the particle that determines the chemical properties of an element. However, an atom is a very small-sized particle, of about 10^-10m.

Based on how small a particle is, it cannot be seen with the naked eyes and hence, requires that one uses a microscope to view it.

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 temperature of the gas, in k, not celsius.
