Apatient needs 0.024 g of a sulfa drug. there are 12-mg tablets in stock. how many tablets should be given?

Answer : The number of tablets given should be, 0.5

Explanation :

We are given :

Mass of sulfa drug for a patient = 0.024 g

Total mass of tablets = 12 mg =

(Conversion factor: 1 g = 1000 mg)

To calculate the number of tablets, we divide the total mass of tablets to the mass of sulfa drug for a patient.

Putting values in above equation, we get:

Hence, the number of tablets given should be, 0.5

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.
