Time of Flight (Mass Spectrometry): Example Questions | A-Level Chemistry

[@simdicool5438]

That was honestly such an amazing video, the fact that you started off basic explained everything slowly, even gave us multiple ways of solving the question in addition to giving different question types! Example questions are the way forward please do more of these. Thank you so much

this was so helpful but for finding the mass of an atom i was taught to divide the mass number by avogadros constant is this fine i got the same anser jus found it had less steps

This was so helpful and the speed was so good for someone whos confused, so happy you didnt go a million miles an hour

Is time of flight included in Edexcel AS chemistry latest syllabus?

[@SaeedAli-q3y]

ur the GOAT made me understand this in 15mins

[@RavinduSandaruwan-qh3sq]

[@abdirahmanmohamed7445]

this is a shortcut to a question that wants you to find the time of flight of an ion but it also gives you the time of flight of another, so what you do is the known mass square rooted divided by the unknown mass number square rooted times the number of the known mass numbers time of flight. i learned this from the video link below

why are dividing the Mr 49 by 1000?

[@nafisac3782]

i love u

[@humanaccount2754]

btw guys for the avodagro constant many of u r used to seeing it is 6.023 times 10 to power of -23. But he took that minus and made it into a fraction. Same thing but for ppl to understand what is the minus’s meaning. I think that was his intention. الله أعلم jazaakAllaahu khairan bro. Very good broken down info .
