Question

number of moles in 0.112 ml of NH3 at stp

Answer 1

$\huge \text{\underline {ANSWER}}$

Number of moles = 5 * 10⁻⁶ moles

$\huge \text{\underline {EXPLANATION}}$

We know that,

Number of moles = Volume(In litres) / 22.4

In the given question,

Volume(in litres) = 0.112 ml = 0.112 * 10⁻³ litre = 11.2 * 10⁻⁵ L

Substituting this value we get,

Number of moles = 11.2 * 10⁻⁵ / 22.4

                             = 0.5 * 10⁻⁵ mole

                             = 5 * 10⁻⁶ moles
