How many moles of hydrogen gas are present in a 50 liter steel cylinder if the pressure is 10 atm and the temperature is 27 degrees Celsius?

12.2 moles of H₂

Explanation:

P . V = n . R . T is the Ideal Gases Law, which is useful to solve this:

First of all, we need to convert the T°C to T° K

T° K = T°C + 273 → 27°C + 273 = 300 K

Let's replace the data given: 10 atm . 50L = m . 0.082L.atm/m.K . 300K

500 L.atm / 0.082L.atm/m.K . 300K = m

12.2 moles = n

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
