Describe how you might prepare disodium phosphate given a solution of phosphoric acid, 0.500 molar and a solution of sodium hydr
1 answer:
<em>Explanation:</em>
When 2 moles of sodium hydroxide (NaOH) reacts with 1 mole of phosphoric acid (H3PO4) it gives 1 moles disodium phosphate Na2HPO4 and 2 moles of water.
0.5 molar solution indicates half moles of molecules are present in per ltr solution.
to prepare disodium phosphate you need to dilute phosphoric acid solution to 0.25 molar and add equal quantity of 0.5 molar solution.

Answer: 60.7 g of will be formed.
Explanation:
To calculate the moles :
The balanced chemical reaction is
is the limiting reagent as it limits the formation of product and
is the excess reagent.
According to stoichiometry :
6 moles of produce = 4 moles of
Thus 2.68 moles of will produce=
of
Mass of
Thus 60.7 g of will be formed by reactiong 60 L of hydrogen gas with an excess of
