Question

how many moles of NaOH are contained in 50cm^3 of. 15 M NaOH​

Answer 1

Answer:

4.05×10

−3

moles

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Molarity=\frac{moles}{\text {Volume in L}}Molarity=

Volume in L

moles

Given Molarity of NaOHNaOH = 0.15 M

Volume of NaOHNaOH = 27 ml= 0.027 L (1L= 1000 ml)

Thus Moles=Molarity\times {\text {Volume in L}}=0.15\times 0.027= 4.05\times 10^{-3}Moles=Molarity×Volume in L=0.15×0.027=4.05×10

−3
