Some Basic concepts of Chemistry 🥱😅 Mole concept😂👌

[hemantgoyal]

seriously this is a joke, asking toppers such low questions and testing them..

[Asmitaavocals]

12 g of mg is the correct answer 😄
Btw i searched mole concept in one shot but i got this short😂😂

[arydv]

I searched for mole concept one shot, and see what I got

Waah re... Hoshiyar un logo se ye sab pooch ke kya hoga ... Bichare padh likh ke neet nikaal chuke... Sukoon se khana kha lene do unn bicharo ko

and is 12 mg of magnesium
no.of moles in 9 g of H2O. is = 9/18 = 1/2. 18 = a.w of h2o
no. of moles in 12 g of mg = 12/24 = 1/2. 24 = a.w.o mg

[Md_Asif]

solution:--
1st stape
no of mole in water = given mass/ molar mass = 9 / 18 =0.5 g
again, no of mole in Mg = 12 / 24 =0.5
hence, option A is correct.

# 9 grams of Water
• Moles of Water= 9/18 = 1/2
•Molecules =1/2 Na
1)12 grams of Mg
•Moles=12/24 =1/2
•Molecules= 1/2Na
2)12 grams of C
•Moles= 12/12 =1
•Molecules=1Na
3)17 grams of NH3
•Moles=17/17 =1
•Molecules=1Na
4)11 grams of CO2
•Moles=11/44 =1/4
•Molecules= 1/4Na
So correct option is 1
(12grams of Mg)

Fun fact:-
Suhani herself doesn't know any concept of questions, she just know the answer 😅

[Varshitha]

The correct answer is 12g of megnesium
12/24 equal to 1/2 as the given water of 9g has the ans as same

[Abhishek-ewkg]

Me Commerce student- focusing on different colors of cookies 💀

[aryaalok]

A 12g Mg
Because
No.of mole of Water = given mass /Molar Mass = 9/18 = 0.5 Mole
No . Of mole of Mg = 12/24 = 0.5 Mole
So, Mole of Mg and Water Same and Molecules also same
Thanks 🙏👍

[akashshil]

1st option

12g of magnesium
Converting in moles:- 12÷24:- 0.5 moles
No. Of molecules:- 0.5×6.023×10^23:- 3.011 × 10^23
Similarly, as in 9g of water:- 9/18:- 0.5 moles
No. Of molecules:- 0.5×Avogadro no.= 3.011× 10^23

[EnglishWeakHai]

n=W/M=N/NA
N=W*NA/M
1-9 gram H20
N=9*NA/18(2*1+16)
N=NA/2

A-12 g Mg
N=12*NA/24=NA/2

Hence, option A is correct

[Ksharma-je]

Yaar ab toh chod do in bacho ko bhi chem

[dharaagrawal]

9 gm of water have 0.5Na molecules ....and 12 gm of Mg also have 0.5 Na molecules...so it should be first....

[craftoblast]

nH2O = 9/18 = 0.5

We know, nH2O = nX
and, ∵ nMg = 12/24 = 0.5


∴ nH2o = nX when X is Mg (12g)

∴ Ans → 12 g of Magnesium

[Ayan_Anand]

Ammonia maybe agar ham log, H2O le and ek side NH4 le to as, told 9 gram of water is 18÷2 = 9 gram, and ammonia ka bhi 18÷2= Maybe I'm correct, I did it in my first attempt, so, please don't judge
