Answer:
5.19 x 10²³ molecules of H₂O
Explanation:
1 mole => 6.023 x 10²³ molecules of H₂O
0.861 mole => 0.861mole x 6.023 x 10²³ molecules of H₂O
= 5.19 x 10²³ molecules of H₂O

Answer:
1.17 M
Explanation:
Step 1: Given data
Molar concentration of Li₃PO₄: 0.390 M
Step 2: Write the reaction for the dissociation of Li₃PO₄
Lithium phosphate is a strong electrolyte that dissociates according to the following equation:
Li₃PO₄(aq) ⇒ 3 Li⁺(aq) + PO₄³⁻(aq)
Step 3: Calculate the molar concentration of lithium ions
The molar ratio of Li₃PO₄ to Li⁺ is 1:3. The molar concentration of Li⁺ is 3/1 × 0.390 M = 1.17 M.
