Answer:
(A) is the answer
Explanation:
(A) heat a saturated sugar water solution, dissolve more sugar, then let the solution cool
In this question, XB3(aq) is an ionic compound which will have the releasing of 3 B⁻ ions ions in water for every molecule of XB3 that dissolves.
XB3(s) --> X+(aq) + 3 B⁻(aq)
[B⁻] = 0.22 mol XB3/1L × 3 mol B⁻ / 1 mol XB3 = 0.66 M
The answer to this question is [B⁻] = 0.66 M
Answer:
0.167
Explanation:
Molar mass of NaOH = 40
40 g of NaOH = 1 mole
5 g of NaOH = 0.125 moles
1000 ml = 1 L
750 ml = 0.75 L
Molarity = 0.125 / 0.75 = 0.1666
Approximately = 0.167
