Acompound of phosphorus and chlorine contains 3.00grams of phosphorus and 10.3 grams of chlorine. how many grams of phosphorus would be in a sample of the compound containing 17.2 grams of chlorine?

mass of phosphorus = 5.01 g

Explanation:

Given data:

Mass of chlorine in sample = 10.3 g

Mass of phosphorus in sample = 3.00 g

Mass of chlorine in same sample = 17.2 g

Mass of phosphorus in this sample = ?

Solution:

To solve this problem we will use cross multiplication method.

Mass of phosphorus / mass of chlorine = Mass of phosphorus / mass of chlorine

3.00 g / 10.3 g =  x / 17.2 g

0.29126 × 17.2 g = x

x = 5.01 g

So the sample with 17.2 gram of chlorine will have 5.01 gram of phosphorus in it.

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.
