    Hi guys,
    I was attempting do these questions but I have no idea where to start!! I asked my teacher to help me but he just refused so I was hoping a few of you could help me.

    All of these questions require you to use:

    coefficient x mol(reactant 1) = coefficient x mol(reactant 2)

    and for solids:

    mol = mass/relative mass

    and for solutions

    mol = molarity x volume

    Thank you so much!! And sorry if this seems like a stupid question but I was wondering what coefficient you mean.

    The coefficient of each component in the balanced stoichiometric equation.

    I was wondering since our upcoming chemistry exams are coming up if people wanted to be part of a chemistry whatsapp revision group. If you are interested either pm me or responded to this message
