Question

calculate molarity of a solution containing 20 gm NaOH per 300ml solution

Answer 1

Answer:

Molarity is a concentration term in which the no. of moles and the volume are related.

Molarity(c)=no of moles(n)/volume in L(V)

here,

n=10/40

And V= 300ml=0.3

So, c=n/v

=10/40*0.3

=0.075 molar

Answer 2

Answer:

Calculate the molarity of the solution. 20 gr of NaOH correspond to 0.5 moles which are contained in 0.5 liter of solution. In one liter of solution there will be (2)(0.5) = 1 mole and thus the solution is 1 M. 5.
