Answer:
Explanation:
From the 1 g sample you have:
0.546 grams of cobalt chloride
1-0.546=0.454 grams of water
Now:
1) The salt
Of the 0.546 g, 0.248 g are cobalt (Mr=58.9) and the rest id Cl (Mr=35.45):
Dividing:
So the molecular formula will be:
2) The water
The water's molecular weight is M=18 :
Bonding with the Co:
The complete formula of the hydrate:
Answer:
The answer is
<h2>1479.60 mL</h2>Explanation:
In order to calculate the volume needed we use the formula
where
C1 is the concentration of the stock solution
V1 is the volume of the stock solution
C2 is the concentration of the diluted solution
V2 is the volume of thevdiluted solution
From the question
C1 = 1.45 M
V1 = 25 mL
C2 = 0.0245 M
So we have
We have the final answer as
<h3>1479.60 mL</h3>Hope this helps you
