Answer:
M(NaOH) = 0.0789 M
Explanation:
NaOH + HCl ---> NaCl + H2O
M(NaOH)*V(NaOH) =M(HCl)*V(HCl)
M(NaOH) *45.0 mL (NaOH) = 0.12 M(HCl) * 29.6 mL(HCl)
M(NaOH) = 0.12*29.6/45.0 = 0.0789 M
Convert 3.00 moles of MgO to moles of Fe2O3
71.8 g of iron (III) oxide (Fe₂O₃) were produced from 3 moles of magnesium oxide (MgO).
Explanation:
We have the following chemical reaction:
2 FeCl₃ + 3 MgO → Fe₂O₃ + 3 MgCl₂
We see from the chemical reaction that 3 moles of magnesium oxide (MgO) will produce 1 mole of iron (III) oxide (Fe₂O₃).
number of moles = mass / molar weight
mass = number of moles × molar weight
mass of Fe₂O₃ = 1 × 71.8 = 71.8 g
