Sir B5 c I think the number of moles had to be 0.1

[@machikomindstutoring7148]

@@shmateophiri805 I will revisit the question

[@bennysinyinza-ik2qu]

Thanks a lot sir but l think you made a mistake on section B, question B5 part C.On finding the number of moles for calcium nitrate=n[Ca(NO3)2],on dividing 16.4g with 164g/mol,you punched 193g/mol instead of 164g/mol that's why it has given you 0.08mol,it is giving 0.1mols.Thank you.

Question 5 the answer is D. Which is iodine not fluorine my brother​@@machikomindstutoring7148

[@Hobbykalenga]

Thanks🙏

[@machikomindstutoring7148]

Yhu are welcome

[@ICIsaac]

Thanks it really helped me, ❤

[@IsabelaNamwinga]

Nice sir

[@justsimp256]

This helped me a lot😭. Thank you so much . May God bless you for what you do

[@machikomindstutoring7148]

Am humbled

[@shmateophiri805]

Wow thank you sir

[@LucaMumba-no8op]

I need more lesson on mole concept

[@goodsonkunda3294]

Make a video also on dilution (mole concept) sir

[@machikomindstutoring7148]

It's there

Sir is not clear you are doing a good job

[@machikomindstutoring7148]

Improve the quality

[@NchindikaNchindika]

You have left one question on uses of nitrogen

[@kelvinchangwe2555]

The number of moles of calcium nitrate is 0.1 not 0.08,just a correction

[@RachealPhirimusonda-bc4so]

The lessons are good now the volume and video to low

[@machikomindstutoring7148]

Noted

[@PhiriJamez-wv1wj]

What topics do usually come in science p2

[@machikomindstutoring7148]

Let me look at the syllabus

[@katongomwila3058]

Sir on question 5 16.4 divide 164 is it not 0.1 am a little behind

[@GraceChirwa-o4u]

Same here

[@eliasmbewe3357]

Yeah it is And I think that was a mistake

[@CharityMweetwa-uw3ib]

Sir am asking to show it clear

[@machikomindstutoring7148]

Is it the whole paper or some questions

[@mwakasibajene3628]

5c complicated answers

[@machikomindstutoring7148]

Yhu need to understand first how to use mole ratios

[@givenmalyamba1720]

Am still behind on mol ratio

[@machikomindstutoring7148]

I will make a video on that

[@kingsnave]

Boss send this paper on app line pliz

[@DavidIvwananjiSiwakwi]

You made a mistake

[@thelmamwewa9493]
