Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the volume of the new solution by using the general formula of dilution:
In such a way, we solve for the final volume, V2, to obtain:

Answer:
<h2>10 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 2 × 5
We have the final answer as
<h3>10 g</h3>
Hope this helps you
Answer:
0.278 mol HCl
Explanation:
We currently have 185.0 mL of a 1.50 mol/L solution of HCl. We want to find the number of moles there are.
Based on the given information, our volume is 185.0 mL and our molarity is 1.50. Because molarity is defined as moles / Litre, we can easily find the moles given volume by multiplying molarity by volume.
First, though, we must convert millilitres to litres. There are 1000 mL in 1 L, so divide 185.0 by 1000:
185.0 / 1000 = 0.185 L
Now, multiply 0.185 by 1.50:
0.185 L * 1.50 mol/L = 0.278 mol HCl
Thus the answer is 0.278 mol HCl.

5 protons and six neutrons
The answer is
<span>HF + H2O <--> H3O(+) + F(-)
</span>
<span>HF + H2O gives H3O(+) + F(-)
and </span>
H3O(+) + F(-)
gives <span>HF + H2O
it is a reciprocal reacation, so </span>
<span>reactions are both reactants and products </span>
