The volume of 2.75 M solution of NaOH required to make 500.0 ml of a 1.27M solution of NaOH is 230.9 Ml


calculation


by use of M1V1=M2V2 volume formula where


M1=2.75 m

V1=?

M2= 500 Ml

V2= 1.27 M


make V1 the subject of the formula V1= M2V2/M1


V1 is therefore= 500Ml x 1.27 M/ 2.75 M = 230.9 Ml

Answer:

V_1=230.9mL

Explanation:

Hello,

This is about a dilution exercise which could be mathematically solved by taking into account that during the dilution process the moles are conserved:

n_1=n_2

Now, as the moles could be expressed in term of molarity an volume one defines:

M_1V_1=M_2V_2

Then, we're asked to report V_1 as it is the volume we need to take from the inital 2.75M solution of NaOH, thus:

V_1=\frac{M_2V_2}{M_1} =\frac{1.27M*500.0mL}{2.75M}\\V_1=230.9mL

Best regards.

A student prepares a 0.47mM aqueous solution of acetic acid CH3CO2H. Calculate the fraction of acetic acid that is in the dissoc
Aliun [14]

The fraction of acetic acid that is dissociated is 0.18

Why?

The chemical equation for the dissociation of acetic acid (HAc) is the following:

HAc(aq) + H₂O(l) ⇄ H₃O⁺(aq) + Ac⁻(aq)

To find the fraction of acetic acid that is in the dissociated form (f), we apply the following equation (Ka for acetic acid is 1.76*10⁻⁵). This equation comes from solving the equation of the equilibrium constant for the dissociated fraction of HAc:

f=\frac{-Ka+\sqrt{Ka^{2} +4KaC} }{2C} = 0.18

Have a nice day!
