The gram formula mass of a compound is 48 grams. the mass of 1.0 moles of this compound is

(1) 1.0g
(2) 4.8g
(3) 48g
(4) 480g

The mass of 1.0 moles of this compound is (3) 48g.

Explanation:

The gram formula mass is defined as the amount of mass in 1.0 moles of a compound.

For example :

For the water, we can calculate its gram formula mass using the molecular formula of the water : To calculate the gram formula mass we need the molecular mass of H (hydrogen) and O (oxygen).

μ(H) =

μ(O) = ⇒ The gram formula mass of water is:

2 [ μ(H) ] + μ(O) =

So 1 mole of water contains 18 grams of water.

In the exercise, the gram formula mass of a compound is 48 grams. Therefore, 1 mole of the compound contains 48 g of compound.

Finally, the correct option is (3) 48g
