4 0

Answer:

Similarity - 1 mol of NaOH in 1M and 1m.

Difference - 1M - 1 mol NaOH in 1L solution,

1m - 1 mol NaOH in 1000g solvent (water).

Explanation:

M - Molarity, the number moles of solute are dissolved in 1 L of solution.

m - Molality is the number of moles of solute per 1 (kg) kilogram = 1000 g of solvent.

Similarity - 1 mol of NaOH in 1M and 1m.

Difference - 1M - 1 mol NaOH in 1L solution,

1m - 1 mol NaOH in 1000g solvent (water).

Calculate hydrochloric acid (umol)in 200 ul of a 0.5173Msolution of acid?

strojnjashka [21]

Answer: The moles of hydrochloric acid is $1.0346\times 10^{-4}\mu mol$

Explanation:

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}$

Or,

$\text{Molarity of the solution}=\frac{\text{Micro moles of solute}\times 10^6}{\text{Volume of solution (in }\mu L)}}$

We are given:

Molarity of solution = 0.5173 M

Volume of solution = $200\mu L$

Putting values in above equation, we get:

$0.5173M=\frac{\text{Micro moles of HCl}\times 10^6}{200\mu L}\\\\\text{Micro moles of HCl}=1.0346\times 10^{-4}\mu mol$

Hence, the moles of hydrochloric acid is $1.0346\times 10^{-4}\mu mol$
