<span>The molar volume of ammonia at standard temperature and pressure (STP) is 22.4L. This is the standard molar volume of any gas at these conditions.</span>
Answer:
<h2>0.52 moles </h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula

where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have

We have the final answer as
<h3>0.52 moles</h3>
Hope this helps you
Answer:
no.
Explanation:
only one planet would be made gas
is earth. and for what you mean like when
planet would be made of gas my answer is no
because theirs so gravity but im not the one
who's deciding and god is the one who's deciding
if when is the other planet having a gas
i know im wrong
2.3*10^-2 M/s IS THE ANWSER<span>

volume of Ni = 25 nL = 25 x 10⁻⁹ L
mol Ni = 25 x 10⁻⁹ L x 1.25 mol/L = 3.125 x 10⁻⁸
mass = mol x Ar Ni
mass = 3.125 x 10⁻⁸ x 59 g/mol
mass = 1.84 x 10⁻⁶ g = 1.84 μg
