Answer:
C. 100.60oC
Explanation:
Find the molality of the solution first, 1.16 m. Then, multiply by the Kb of 0.52. Then, add that number to the boiling point of pure water (100o). This is the new boiling point of the solution 100.60o.

Answer:
0.07789 M is the sodium hydroxide concentration.
Explanation:
Mass of potassium hydrogen phthalate = 0.6986 g
Molar mass of potassium hydrogen phthalate = 204.22 g/mol
Moles of potassium hydrogen phthalate = 
According to reaction , 1 mole og KHp reactswith 1 mole of NaOH , then 0.003421 moles of KHp will react with :
Moles of NaOH = 0.003421 mole
Volume of NaOH solution = 43.92 ml = 0.04392 L ( 1 mL = 0.001L)
Concentration of NaOH :
0.07789 M is the sodium hydroxide concentration.
Answer:
3.01×10²⁴ atoms
Explanation:
Our compound is the Na₃PO₄
Sodium phosphate.
We assume, we have 5 moles of the mentioned salt.
1 mol of anything contains 6.02×10²³ atoms.
That's the Avogadro's number. The conversion is:
5 mol . 6.02×10²³ atoms /1mol = 3.01×10²⁴ atoms
