Mole Concept

I am 8 grade but my intellectual level is 11 grade

Thank you sir

1) 96g
2) 22.4L
3) 18×1.67×10^-24

For table salt NaCl term formula mass is used insted of moleculer mass.

(1) Formulae of ammonium carbonate is (NH4)2CO3
Molar mass=(14+1×4)2+12+16×3
18×2+12+48
36+12+48
96u mass
Hence for 1 mole of ammonium carbonate it's mass will be 96g
(2)Molar mass of Nitrogen gas is 7×2=14u
So for 1mole of Nitrogen gas it's mass will be 14g
Hence for 140gram of Nitrogen gas it's number of moles becomes =140÷14
=10moles
At STP volume of 1mole of Nitrogen gas is 22.4L
Hence for 10moles of Nitrogen gas it's volume becomes 22.4×10=224L

Hello sir, isn't the molar volume 24litres

Am here from kisii university kenya
A biotechnologist 😅😅😅
I really love and enjoy your content

Sir, please try to cover 9th 10th 11th and 12th syllabus of science

thank uuu, amazing explanation

Solution of the questions
(1) Formulae of ammonium carbonate is (NH4)2CO3
Molar mass=(14+1×4)2+12+16×3
18×2+12+48
36+12+48
96u mass
Hence for 1 mole of ammonium carbonate it's mass will be 96g
(2)Molar mass of Nitrogen gas is 14×2=28u
So for 1mole of Nitrogen gas it's mass will be 28u
Hence for 140gram of Nitrogen gas it's number of moles becomes =140÷28
=5moles
At STP volume of 1mole of Nitrogen gas is 22.4L
Hence for 10moles of Nitrogen gas it's volume becomes 22.4×10=224L

Very intuitive

Thanks

1) 96g
2) 22.4 L
3) 18 × 1.67 × 10^-24

answers

Is 1 mole =6.023×10²³ Or 6.022×10²³?

thank you very much!

Please clarify...
Relative Molecular Mass has no unit and Molecular Mass does.
Please is that correct?

1) 96
2) 5
3) 2.988 × 10^-26

Anyone who is here in 2024😢😂

amazing explanation

i was clear from mole concept 80% now 100 %

It's really a nice way of teaching
Thank you so much❤

Qn1:122g
Qn2: 14moles
Qn3: 0.018kg

❤❤❤❤❤❤

❤

1. 96

2. 5 moles
112

3. 3X10^-26 [as I took Avogadro number as 6X10^23]

The mole for a substance relates the mass and the number of the particles. The particles may either be mono-atomic or poly-atomic

This mole concept explanation is so good it blew my mind!!!

i want the solutions of the 3 top questions

Wearing the jacket was completely unnecessary

Your method is interesting

1)96 2)5moles 3)2.989×10^‐26 is this crct sir

Thank you so much teacher.... this topic is very hard for me if not you, this topic would have confuse forever. Thank you

1) 96g
2)5mol
3)2.989×10^ -26kg

Thank you so much sir 🙏❤️🙏 really you just amazing 🙏🙏

1. 96g
2. 5moles and 112 litres
3. 3 X 10^-26kgs (I took Approximate value of Avagdro number to 6X10^-23

Heyy you watching in 2024

Yo

thanks for making me achemist. am Agah from uganda Kyenjojo

Who say that for Nacl we use molecular mass U r wrong

Sir u r not simplyfied avagadro number this is dificult to bipc students

Thank you sir...❤it is the best explanation

Thank you
