Question

0.224ml of ch4 at ntp =___mol?​

Answer 1

Answer:

0.00001 moles

Explanation:

1 mole of a gas occupies 22.4 litres or 22400 ml at NTP.

Therefore if 1 mole= 22400ml then. (cross multiply)

x mole=0.224ml

x=0.224/22400

x=0.00001 moles

Answer 2

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

0.224ml of CH₄ = 10⁻⁵ moles

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

Given,

Volume of CH₄ = V = 0.224ml

                                = 0.224 * 10⁻³ litre

                                = 22.4 * 10⁻⁵ litre

We know that,

Number of moles = Volume in litres / 22.4

n = V / 22.4

n = 22.4 * 10⁻⁵ / 22.4

n = 10⁻⁵ moles
