Explanation:

There is some info missing. I think this is the original question.

A chemist dissolves 707.mg of pure sodium hydroxide in enough water to make up 100.mL of solution. Calculate the pH of the solution. (The temperature of the solution is 25°C.) Be sure your answer has the correct number of significant digits.

Step 1: Calculate the molarity of NaOH

M = mass of solute / molar mass of solute × liters of solution

M = 0.707 g / 40.0 g/mol × 0.100 L

M = 0.177 M

Step 2: Write the basic dissociation reaction

NaOH → Na⁺ + OH⁻

The molar ratio of NaOH to OH⁻ is 1:1, Then, [OH⁻] = 0.177 M.

Step 3: Calculate the pOH

pOH = -log [OH⁻]

pOH = -log 0.177

pOH = 0.752

Step 4: Calculate the pH

pH + pOH = 14.00

pH = 14 - pOH = 14.00 - 0.752

pH = 13.25

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

the answer to this question is 3.
