The solution would be like this for this specific problem:
4 NaOCl + S2O3{2-} + 2
OH{-} → 2 SO4{2-} + H2O + 4 NaCl
<span>(0.00456 L) x (0.100 mol/L
S2O3{2-}) x (4 mol NaOCl / 1 mol S2O3{2-}) x (100.0 mL / 25 mL) x </span><span>
<span>(74.4422 g NaClO/mol) = 0.54313 g </span></span>
<span>(5.00 mL) x (1.08 g/mL) =
5.40 g solution </span>
(0.54313 g) / (5.40 g) =
0.101 = 10.1%
So, the average percent by mass of NaClO in the
commercial bleach is 10.1%.

<em> Hi mate, here is ur answer:</em>
<em />
<em>You can </em><em>dissolve</em><em> more </em><em>salt</em><em> in </em><em>hot water</em><em> because in hot water, </em><em>molecules </em><em>move faster than </em><em>cold water</em><em> because of the </em><em>higher energy</em><em>, as a result the molecules of hot water move fast and </em><em>settles down</em><em>. As they settle fast, it is easy for higher amount of salt to dissolve in hot water. </em>
<em>HOPE THIS HELPS U</em>
<em>:) WISHING U A GREAT DAY AHEAD </em>
Answer:
The mole was previously defined as the number of atoms determined experimentally to be found in 12 grams of carbon-12. The number of units in a mole also bears the name Avogadro's number, or Avogadro's constant, in honour of the Italian physicist Amedeo Avogadro.
Explanation:
I'm not entirely sure if i'm right but I hope this helps.
The statement that the friend made is not true. most of the mass of the plant is from carbon. the carbon comes from carbon dioxide which is used during photosynthesis. the left over carbon from photosynthesis is used to to help the plant gain mass. there is a process for this which is called cellular respiration
