In order for a solute to dissolve in a solvent,
the attractive forces between solute particles and the solvent particles must
be stronger than the attractive forces between solute-solute and
solvent-solvent particles. This is important so that the solute will remain in
solution.
<u>Answer:</u>
<em>0.264 g of 
can be formed from 288 mg of 
</em>
<u>Explanation:</u>
The balanced chemical equation is
The conversions are
Mass in mg is converted to mass in g
Mass in g is converted to moles by dividing with molar mass
Moles is converted to moles by using the mole ratio of 
is 9 : 6
Moles is converted to mass by multiplying with molar mass
mass in mg > mass in g >moles > moles > mass
=0.264g (Answer)
Answer:
<h3>The answer is 1.99 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 16.93 g
volume = final volume of water - initial volume of water
volume = 19.7 - 11.2 = 8.5 mL
We have
We have the final answer as
<h3>1.99 g/mL</h3>

Answer:
percentage dissociation of trimethylacetic acid in a 0.57M aqueous solution = 0.40%
Explanation:
check attachment below for more information o the answer.
Answer is: concentratio of H₃O⁺ ions is 4.2·10⁻³ M.<span>
Chemical reaction: HCOOH(aq) + H</span>₂O(l) ⇄ HCOO⁻(aq) + H₃O⁺(aq).<span>
c(HCOOH) = 0,1 M.
[</span>H₃O⁺] = [HCOO⁻] = x.<span>
[HCOOH] = 0,1 M - x.
</span>Ka = [H₃O⁺] · [HCOO⁻] / [HCOOH].
0,00018 = x² / (0,1 M - x).<span>
Solve quadratic equation: x = </span>[H₃O⁺] = 0,0042 M.
