H3P polar or non polar

Hover for more information. Phosphine is an example of a polar molecule with non-polar bonds. ... The lone pair of electrons on phosphorus causes the molecule to be asymmetrical with respect to charge distribution and that's why the molecule is polar even though it has non-polar bonds. Its shape is trigonal pyramidal.

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

sry but any answer choices
