Question

50 ml of 0.1 M HCL contains​

Answer 1

Answer:

49.9 the 50 ml of 0.1 M HCL contains

Answer 2

Given:

50 ml of 0.1 M HCL

To find:

No. of moles of HCL contained in 50 ml of 0.1 M HCL

Solution:

The formula of molarity or molar concentration is given as,

$\boxed{M\:=\:\frac{n}{V(in\: litres)} }$

where

n = no. of moles of the solute

V = litres of solution

M = molarity or molar concentration

Here we have,

Molarity of HCL = 0.1 M

Volume = 50 ml =  $\frac{50}{1000}$ = 0.05 L

Now, substituting the given values in the formula, we get

0.1 = $\frac{n}{0.05}$

⇒ n = 5 × 10⁻³ moles

Thus, 50 ml of 0.1 M HCL contains​ 5 × 10⁻³ moles of HCL.
