Why is helium nucleus containing no neutrons is likely to be unstable

Chemistry
1 answer:
jolli1 [7]3 years ago

<span>A Helium nucleus is likely to be unstable if it has no neutrons because the remaining protons will repel electromagnetically and basically cause the atom to fall apart. The neutrons could have helped in holding everything together, and not make the protons repel.</span>

What is the molarity of a stock solution if 60 mL were used to make 150 ml<br>of a .5M solution? ​
olga2289 [7]

The molarity of the stock solution is 1.25 M.

<u>Explanation:</u>

We have to find the molarity of the stock solution using the law of volumetric analysis as,

V1M1 = V2M2

V1 = 150 ml

M1 = 0.5 M

V2 = 60 ml

M2 = ?

The above equation can be rearranged to get M2 as,

M2 = $\frac{V1M1}{V2}

Plugin the values as,

M2 = $\frac{150 \times 0.5}{60}

       = 1.25 M

So the molarity of the stock solution is 1.25 M.
