Answer:
37.25 grams/L.
Explanation:
- Molarity (M) is defined as the no. of moles of solute dissolved per 1.0 L of the solution.
<em>M = (no. of moles of KCl)/(volume of the solution (L))</em>
<em></em>
∵ no. of moles of KCl = (mass of KCl)/(molar mass of KCl)
∴ M = [(mass of KCl)/(molar mass of KCl)]/(volume of the solution (L))
∴ (mass of KCl)/(volume of the solution (L)) = (M)*(molar mass of KCl) = (0.5 M)*(74.5 g/mol) = 37.25 g/L.
<em>So, the grams/L of KCl = 37.25 grams/L.</em>
Answer:
I think it is Volume.
Explanation:
An extensive property is a property that depends on the amount of sample present.
The theory of blending inheritance was used to describe an actual blending of our alleles, that together would form a new allele. For example, skin color and height would be the result of the blend of the parent's alleles.
This theory doesn't explain why some traits disapear or are discrete.
On the other hand, Mendel's experiments with seed colors explains it. He demonstrated that genes are inherited in pairs and that in hybrid organisms, dominant versions of that gene, could hide the presence of a recessive version of that same gene.
So what’s the question? I’m confused
Answer:
The volume of HCl required is 
Explanation:
From the question we are told that
The chemical equation for this reaction is
The mass of Al is 
The concentration of HCl is 
The number of moles of 
given is 
The molar mass of Al is 
So
From the balanced equation
2 moles of Al reacts with 6 moles of HCl
So 0.07 moles of Al will react with x
Therefore
Now the volume of HCl can be obtained as
So
