Question

how will you prepare 1.0×10^-2 m NaOH from 0.1m NaOH stock solution?​

Answer 1

◇Required, 0.01 M of NaOH from 0.1 M stock sol.

For stock solution:

Let the volume of stock sol. be 1 litre.

Molarity = 0.1 M

Molarity = (moles of solute)/(liters of solution)

0.1 = moles/1

moles of NaOH = 0.1 moles

What volume of 0.01 M NaOH will have 0.1 moles of NaOH in it = ?

For 0.01 M NaOH:

Molarity = 0.01 M

Moles of NaOH = 0.1 moles

volume of soln = ?
