Answer 3

can you please help me?

Answer 4

what's No2? :P

1. express it in an equation form, e.g. aA + bB <-> cC
2. build a ratio using the stoichiometric coefficients
\(\dfrac{n_A}{a}=\dfrac{n_B}{b}\)

assume an arbitrary amount in moles, and find the moles of the other reactant.

3. convert both to mass
4. add the mass up and find the percent each contributes to the total weight
