Question

How many grams of aluminum are present in 0.2 mole of it?

Explanation required!

Answer 1

Molar mass of Aluminium = 27g
so,Mass of 1 mole of Al = 27 g
Mass of 0.2 mole of Al = 27 x 0.2 = 5.4 g

so 5.4 g Al is present in 0.2 gm of Aluminium.

Answer 2

Hello Dear.

Here is the answer---

Given⇒
No. of moles of the Aluminum = 0.2 moles.
Molar Mass of the Aluminium  = 27 g/mole.

Now, Using the Formula,

 No. of moles = Mass/Molar Mass.
 0.2 × 27 = Mass
⇒ Mass = 5.4 g.


∴ Mass of the Aluminum is 5.4 g.


Hope it helps.
