How many molecules in 2.5g of water?Watch
So In 2.5 g you have 2.5/18 Moles of water. 2.5/18 * Avogadro constant gives you the number of molecules. This should be 8.37 x 10^22 molecules.
Number of moles = mass/molecular mass
1 mole is 6.02 x10^23 molecules
0.138 x 6.02 x 10^23 = 8.36 x 10^22 molecules
Lol you're confidently stating false information. You're the ignorant one. One molecule doesn't weigh one gram. One molecule is so infinitisimally small you really think it weighs one gram? Do your research before spewing your false information on here
I'm done😂😂😂. You're deluded. If your chemistry teacher told you that there's no hope for you. Wonder how teaching standards can get that low. And if you wrote that in your resit you may have to resit chemistry yet again. Please google this and you will see I'm telling the truth.
Well sh*t ive done chemistry all wrong
