Answer: 368 grams of sodium reacted.
Explanation:
The balanced reaction is :
According to stoichiometry :
2 moles of 
are formed from = 2 moles of 
Thus 16 moles of are formed from=
of
Mass of 
Thus 368 grams of sodium reacted.
Answer:
1. a simulation 2. saurology
Explanation:
The complete balanced chemical equation for this is:
<span>3KOH + H3PO4
--> K3PO4 + 3H2O</span>
First we calculate the number of moles of H3PO4:
moles H3PO4 = 0.650 moles / L * 0.024 L = 0.0156 mol
From stoichiometry, 3 moles of KOH is required for every
mole of H3PO4, therefore:
moles KOH = 0.0156 mol H3PO4 * (3 moles KOH / 1 mole
H3PO4) = 0.0468 mol
Calculating for volume given molarity of 0.350 M KOH:
Volume = 0.0468 mol / (0.350 mol / L) = 0.1337 L = 133.7
mL
Answer:
<span>133.7 mL KOH</span>
