If 100mg of CuO is mixed with 1mL of 1M H2SO4, how much CuSO4 can be formed (in moles)
The first step is to write down the chemistry and show what is happening! ALWAYS. And make sure that the equation is written down \(\sf \color{red}{balanced}\).
CuO + H2SO4 --> CuSO4 + H2O
Copper (II) oxide mixed with sulfuric acid \[\sf CuO(s) + H_2SO_4 (aq) \to CuSO_4(aq) +H_2O(l)\] balanced?
If it's balanced properly, this will help you in your mole-to-mole ratio in using copper(II) oxide to find the number of moles of copper(II)sulfate,
Since you are given 100 mg of copper(II) oxide, you want to change that to grams first. \[\sf 100 ~\text{mg} \times \frac{10^{-3} ~\text{g}}{1~\text{mg}} = ~?\]
Then use the amount of grams to convert from \[\text{grams}\to \text{molar mass} \to \text{mole to mole ratio}\]To find the # of moles of \(\sf CuSO_4\)
Wrong.
