Question

frdzz solve this one plzz its a question from jee no. 11. i need full explanation no shortcut plzz ​

Answer 1

Answer is ii) and

explanation.......

25g/0.5mol = 50g/mol

There are 4 mol of chlorines

50g/mol* 4mol = 200g

Answer 2

Answer:

Option (II)

Explanation:

First let me create a mind map to solve such questions  , in this type of questions

⇒ Find out   first  tht what  information u are getting from question

Find out  the molecular mass of given compound using mole concepts

⇒2nd most ,  probably , one get confused abt a sentence '' number of atoms in a compound " tht means number of atoms of a given element in a compound ,but dont misunderstand on writing it its actual existence form for ex - here in  MCl4  number of atoms of Cl are 4 not 2 (one get confused in Cl2 , O2 etc,,,)

I hope u hve understood this new concept

so let me answer it -

Given mass (m) of Cl in  MCl4  =  2.5 g

Number of moles (n) =0.5 mole

mass of one Cl atom = m/n = 25/.5 = 50g/mol

Mass of 4 cl atoms = 4*50 = 200gm/mol
