What do scientists do to easily share measurements data they can understand
Stells [14]

These days, scientists all over the world use a standard system of measurements.  It's the SI or metric system.

What about scientists in the United States, Liberia, and Burma ?  These three countries are the only ones in the world that haven't adopted the metric system.  What do THEY do ?Easy.  When scientists in those countries are off work, they use the inches, yards, feet, quarts, miles and gallons that everybody around them is using.  But when they go to work, they use the same metric system that everyone else in the world is using.

At 25 °C, only 0.0990 mol of the generic salt AB3 is soluble in 1.00 L of water. What is the Ksp of the salt at 25 °C? AB3(s)↽−−
maksim [4K]

Answer:

Ksp=2.59x10^{-3}

Explanation:

Hello,

In this case, given the 0.0990 moles of the salt are soluble in 1.00 L of water only, we can infer that the molar solubility is 0.099 M. Next, since the dissociation of the salt is:

AB_3\rightleftharpoons A^{3+}+3B^-

The concentrations of the A and B ions in the solution are:

[A]=0.099 \frac{molAB_3}{L}*\frac{1molA}{1molAB_3}  =0.0099M

[B]=0.099 \frac{molAB_3}{L}*\frac{3molB}{1molAB_3}  =0.000.297M

Then, as the solubility product is defined as:

Ksp=[A][B]^3

Due to the given dissociation, it turns out:

Ksp=[0.099M][0.297M]^3\\\\Ksp=2.59x10^{-3}

Regards.

On heating 5.03 g of hydrated barium chloride (BaCl2 XH2O), 4.23 g is left behind. What is the name of this hydrate? (
RSB [31]

<span>1)    </span><span>Deduce the two masses and see the amount of water was driven off when heated: </span><span>

<span>5.03 g - 4.23 g = 0.8 g H2O given off </span>

<span>2) Change mass from grams to moles of H2O: </span>

<span>0.8 g H2O / 18 g H2O in 1 mole = 0.044 mol H2O </span>

<span>3) Change left over mass to moles  of BaCl2 .</span></span>

<span>
<span>4.23 g BaCl2 / 207 g BaCl2 in 1 mol = 0.021 mol BaCl2 </span>

<span>4)Find the ratio of mol H2O to mol BaCl2: </span>

<span>0.044 mol H2O : 0.021 mol BaCl2 </span>

<span>5) The resulting  ratio is  2:1 so two H2O for each BaCl2, thus,  the hydrate was named: </span>
<span>Barium chloride di-hydrate</span></span>
