A chemist wants a 0.100 m solution of naoh. She has 0.0550 mol naoh available. What volume of solution is needed to make the mixture?

She has to mix 0.0550 moles of NaOH in a 550 mL solution to make a 0.100 M solution

Explanation:

Step 1: Data given

Concentration of the solution = 0.100 M

Number of moles NaOH = 0.0550 moles

Step 2: Calculate the volume of solution she needs

Concentration NaOH solution = number of moles NaOH / volume solution

Volume of the solution = Number of moles NaOH / Concentration NaOH solution

Volume of the solution = 0.0550 moles NaOH / 0.100 mol /L

Volume of the solution needed = 0.55 L

Volume of the solution needed = 550 mL

She has to mix 0.0550 moles of NaOH in a 550 mL solution to make a 0.100 M solution

the correct answer is a

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
