Guys post any questions from both physics and chemistry paper 1 that you're having difficulty with

Okay first question:
Which statement about one mole of a metal is always correct:
A it contains s the same number of atoms as 1 mole of hydrogen atoms
B it contains the same number I atoms as 1/12 mole if 12C
C it has the same mass as 1 mole of hydrogen Atoms
D it is liberated by 1 mole of electrons

Is it B?

 

[Snowysangel]

Is it B?

Nope A. I think 12C has one mole of particles..so 1/12 of that would have 1/12th if one mole. I don't get why it's A cause hydrogen doesn't exist as atoms so shouldn't it be one mole of hydrogen gas?

Oh i get it, it means the no. of hydrogen atoms in its one mole

Oh so if it said the same number of molecules as one mole if hydrogen gas it would've been correct too! Post some questions!

I am busy with maths p3 right now
But after 22nd i ll post some Qs
