The number of H atoms in 3(NH₄)₂CrO₄ = 24
<h3>Further explanation </h3>
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
Subscripts in the chemical formula indicate the number of atoms
The compound of 3(NH₄)₂CrO₄ ( 3 molecules of (NH₄)₂CrO₄ ) :
Number of H :

Concentration and ion moles are equal only when volume is 1. Of 1.0 x 10-6 and 1.0 x 10-4, the larger number is 1.
Answer:
182mL
Explanation:
Given parameters:
Molarity of solution = 3.11M
New volume = 232mL = 0.232dm³
New molarity = 2.44M
Unknown:
Volume of original solution = ?
Solution:
We know the full information about the new solution we want to obtain. From this, we should find the number of moles.
Using the number of moles, we can find the original volume.
Molarity =
New number of moles = molarity x volume = 2.44 x 0.232
= 0.57moles
The original volume will be;
Volume = = = 0.182dm³ or 182mL
Yeah what the other person said ^
