Hello everyone
I have a question regarding paper 5 chemistry
When I'm doing calculations, for moles for example, the answer should be in how many significant figures or decimal places ? and then if I use the value again, do I use the exact value ( fraction ) or use the value I got ?
For example there was a question I calculated the number of moles I used 0.3/27 - 0.011...
So I wrote 0.011 for that. and then I had to multiply that number by 3/2 to get number of moles for another element, shall I use 0.3/27 as the value or 0.011 ?
Hope that makes sense.
