a mole is a number , like a dozen
dozen = 12 , mole = 6.02E23
6.02E23 ... atoms
2 * 6.02E23 ... atoms
molar mass is 31 g ... so, 6.02E23
... atoms
molar mass is 18 g ... so, 6.02E23
... molecules
How may particles are there in:
in 1 mole of silicon?
in 2 moles of fluorine?
in 31g phosphorous?
in 18g water?
please help im confused especially with the last one and the second last one second

I thought the last two were different I got
for 31g phosphorous:
5.149501661 X 10-23
for 18g water:
2.990033223 X 10-23
Scott I dont get what you meant by your last two answers
for 31g phosphorous:
5.149501661 X 10-23
for 18g water:
2.990033223 X 10-23

Please note that P is spelled posphorus
the atomic mass of P is 31
... this means that one mole of P has a mass of 31 g
... P is an element, so the "particles" are atoms
similarly with the water question
... water is a compound, so the "particles" are molecules

I see I can't spell phosphorus either.
