Answer:
A
Explanation:
molarity=moles of solute/liter of solution
molarity=0.26/0.3
molarity=0.87molar
Answer:
<h2>93.02 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
![n = \frac{N}{L} \\](https://tex.z-dn.net/?f=n%20%3D%20%20%5Cfrac%7BN%7D%7BL%7D%20%5C%5C)
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
![n = \frac{5.6 \times {10}^{25} }{6.02 \times {10}^{23} } \\ = 93.023...](https://tex.z-dn.net/?f=n%20%3D%20%20%5Cfrac%7B5.6%20%5Ctimes%20%20%7B10%7D%5E%7B25%7D%20%7D%7B6.02%20%20%5Ctimes%20%20%7B10%7D%5E%7B23%7D%20%7D%20%20%5C%5C%20%20%3D%2093.023...)
We have the final answer as
<h3>93.02 moles</h3>
