Can two different elements have same number of moles? example? just sayin'..a random question!

OpenStudy (anonymous):

what do u mean by same number of moles?

OpenStudy (dls):

x gram of an element and x gram of another element give the same number of moles?

OpenStudy (anonymous):

oh.ok

OpenStudy (anonymous):

it cant be

OpenStudy (anonymous):

because there is no 2 elements with the same mass number

OpenStudy (dls):

it depends on mass in gram too.

OpenStudy (lgbasallote):

\[H_2 O + CO_2\] i have 1 mole of water and 1 mole of carbon dioxide...is that what you're asking?

OpenStudy (chmvijay):

it is not possible for elements but it can be possible for molecules having same molecular formula but different structural formula!!!!

OpenStudy (lgbasallote):

oh wait yeah..elements sorry...yup it cant be

OpenStudy (chmvijay):

i dint get ulgbasallote

OpenStudy (unklerhaukus):

isotopes of different element could have the same mass number

OpenStudy (anonymous):

hmmmm....this is a tricky question, because technically 1 mole = 6.022 x 10^23 particles, regardless of the element. So in this sense, a mole of hydrogen would be equal to a mole of say carbon. If you're talking about the weight of one mole compared to another, then no...because elements differ in mass.

OpenStudy (dls):

What I meant is.. number of mole=mass in gram/atomic mass can this formula lead to two same answers for two different elements I know every element differs in atomic mass but by adjusting the mass in gram(increasing or decreasing) can't we get the same answer? something like 0.42 moles etc..?
