Answer:
no le entiendo pero si me se la respuesta ya tu sabe ✨✨✨✨
Answer: 2.4 M
Explanation:
According to the neutralization law,
where,
= molarity of 
solution = 3.5 M
= volume of 
solution = 34.3 ml
= molarity of 
solution = ?
= volume of solution = 50 ml
= valency of = 1
= valency of = 1
Therefore, the concentration of NaOH solution is 2.4 M.
Answer is: D. 6.02 x 1023.
Because this is Avogadro constant<span> (the number of </span>constituent particles, in this example atoms of gold<span> that are contained in the </span>amount of substance<span> given by one </span>mole). <span>The </span>mole<span> is the </span>unit of measurement<span> for </span>amount of substance, t<span>he mole is an </span>SI base unit<span>, with the unit symbol </span>mol<span>.</span>
The answer is B!! hope this helps(: an example is a zebra or a lion
