The molecular clock theory uses genetic traits to estimate how long ago various groups or organisms diverged evolutionarily from one another

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

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

just did the assignment and the answer was #1 +2 n

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
