plz can sm1 give the defination of the mole and avogardos constant ?
I acctually wanted an official defination ..A mole if 6.02x10^23 particles of any substance.
It's basically a unit of measurement if you think about it, like a dozen is = 12, a mole is = 6.02x10^23
Hope this helped x)
thankkkkkkkkkkkkkkkkkkkkkkkk uuuu soooooooooooooo much silly me:/ thank uukainat husain Look,
the question states that u need to draw a circuit which is similiar to (ii) using a lead (connecting wire) and u need to use standard symbols to show AB BC & CD but there is 1 more condition they want u to connect resistors A & D together
so using the symbol of resistor we draw AB & BC now the problem is CD in the diagram(ii) CD is connected to C but not to A so in ur diagram u need to connect it to A wen u do it, this is wat u'll get
Naww, don't give me credit. I posted the answer so you can understand and manipulate it on your own.Not my answer, found this in another thread where a person asked the same question.
"Mark the centre of the cylinder, measure the cylinder.
After the measurement, place it on the metre rule. It should cover up the area we measure (for eg. 2cm)
So it'll cover the area between 8 - 1o and or 9 - 11 and so on..
If length of the cylinder is 2 cm, make sure to place it at 9 cm and so it ends at 11 cm, being 10 in the middle."
Credits for answer go to wooowooowoo
lol no problem n ur most welcumthankkkkkkkkkkkkkkkkkkkkkkkk uuuu soooooooooooooo much silly me:/ thank uu
A mole (molar mass) of any susbtance is it's relative atomic number (AR) or relative molecular mass (Mr) (if it is a compound) measured in gramsI acctually wanted an official defination ..

xperimental acc. i dunnowhat is the limit of experimental accuracy and how do you know if your measurment lies within the limit of experimental accuracy?
also how do you make sure that the center of an object lies within a certain mark on a ruler?
PLEASE i need help asap it has come up a couple of times in the pp's
Thank youu!
