V1xM1 / n1 = V2xM2 / n2

does anyone know for sure if we are not allowed to use this formula, my chemistry teacher mentioned something about it but it seems to pop up in some marking schemes, thanks

Shows up in older marking schemes. You need to find moles using MxV/1000

You can use it to answer questions and get full marks if u get the answer right. But if you get the answer wrong they wont give you attempt marks. They're trying to discourage that formula so id try avoid using it if possible

nah i think you are allowed use it but just for redox titrations, don't call it Mr call it Mred cus Mr is molecular mass and you can lose marks for that. That is all i can think of

@evanccreavan Mred? never saw/heard of that, is it just to show the examiner that you don't mean Mr

@Caoimhe2003 ya that is it, my teacher says you could lose marks but she could just be fussy
