Find the no. of atoms present in 40g of nitrogen gas at STP?

8.60 * atoms N2

Explanation:

We want to convert grams to moles and then moles to atoms.

First, we convert grams of nitrogen gas (which is N2) to moles. To do so, we need the molar mass of N2, which is just 14.01 * 2 = 28.02 g.

40 g N2 * = 1.43 mol N2

Now, we need to convert moles to atoms by using Avogadro's number, which is :

1.43 mol N2 * = 8.60 * atoms N2

Thus, the answer is 8.60 * atoms N2.

yes definetly because you are using energy

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.
