Magnesium has three naturally occurring isotopes, ²⁴Mg (isotopic mass = 23.9850 amu, abundance = 78.99%), ²⁵Mg (isotopic mass =
joja [24]

The atomic mass of the  magnesium is : 24.31⋅g.

<h3>What is isotopes?</h3>

Isotopes are members of a family of elements that all have the same number of protons and different numbers of neutrons. The number of protons in the nucleus determines the atomic number of an element on the periodic table.

Magnesium has three natural isotopes: ²⁴Mg, ²⁵Mg, and ²⁶Mg.

<h3>What is atomic mass ?</h3>

Atomic mass is the mass of an atom. The SI unit of mass is the kilogram, while atomic mass is often expressed in the non-SI unit dalton (synonymous with uniform atomic mass unit). 1 Da is defined as 1/12 the mass of a free carbon-12 atom at rest in the ground state.

Calculation :

The atomic mass is the weighted average of the individual isotopic masses:

(23.99×78.99%+24.99×10.00%+25.98×11.01%)⋅g=24.31⋅g

Question 15 (5 points)
Vladimir [108]

This problem is providing us with the maximum mass of Imitrex a patient can get daily as 0.2 g. Also, the mass of a tablet is given as 25 mg so the number of tablets they get in a day is required. After the calculations, the result turns out to be 10 tablets.

<h3>Dimensional analysis:</h3>

In chemistry, dimensional analysis is used to calculate specific outcomes given useful information to do so. Despite not having specific formulas for every problem, one can come up with a feasible proportional-factor-based setup, in order to obtain the required.

In this case, since the mass per tablet is 25 mg, one can divide the maximum dosage by this mass per tablet, both in grams, to obtain the required number of tablets for a daily dosage:

25\frac{mg}{tablet}*\frac{1g}{1000mg}=0.025\frac{g}{tablet}  \\\\\#tablets=\frac{0.25g}{0.025\frac{g}{tablet}} \\\\\#tablets=10 tablets

The solubility product for an insoluble salt with the formula M2X3 is written as ________, where s is the molar solubility
masha68 [24]

Answer:

36s^5

Explanation:

We have;

M2X3 (s)------> 2M^3+(aq)  + 3X^2-(aq)

If [M^3+(aq)] = [X^2-(aq)] = s

We then have;

Ksp = (2s)^2 * (3s)^3

Ksp = 4s^2 * 9s^3

Ksp = 36s^5

Note that Ksp is known as the solubility product. It is an equilibrum equation that shows the solubility of a solute in water.
