7. What is the mass in grams of 5.90 mol CgH1g? (l point) 0.0512 g
O19.4 g
389 g
O673 g

m = 673 g

Explanation:

We need to find the mass of 5.90 mol of

Molar mass of is:

Let m be the mass of 5.90 mol of . Using mole concept to find it.

No of moles = mass/molar mass

So, the required mass is 673 g. Hence, the correct option is (d).

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it
