Answer:
5 moles
Explanation:
Given data:
Number of moles of HCl = 5 mol
Number of moles of H₂O produced = ?
Solution:
Chemical equation:
HCl + NaOH → NaCl + H₂O
Now we will compare the moles of HCl with H₂O.
HCl : H₂O
1 : 1
5 : 5
5 moles of water will be produced.
2 HClO(aq) + Ca(OH)2(aq) = 2 H2O(l) + Ca(ClO)2(aq) is the balanced equation
Answer:
2.448 M ≅ 2.45 M.
Explanation:
Molarity (M) is the no. of moles of solute that dissolved in 1.0 L of the solution.
M = (no. of moles of solute)/(V of the solution (L).
M = (mass/molar mass) Li₂S / (V of the solution (L))
<em>∴ M of Li₂S</em> = (500.0 g/46.4 g/mol)/(4.44 L) = <em>2.448 M ≅ 2.45 M.</em>
