Explanation:

Molarity is defined as the number of moles of solute present in liter of solution.

Mathematically,         Molarity = \frac{\text{no. of moles}}{\text{Volume in liter}}

Also, when number of moles are equal in a solution then the formula will be as follows.

                     M_{1} \times V_{1} = M_{2} \times V_{2}

It is given that M_{1} is 0.14 M, V_{1} is 0.083 L, and V_{2} is 1.0 L.

Hence, calculate the value of M_{2} using above formula as follows.

                    M_{1} \times V_{1} = M_{2} \times V_{2}

                 0.14 M \times 0.083 L = M_{2} \times 1.0 L

                      M_{2} = \frac{0.01162 M.L}{1 L}

                                  = 0.01162 M

Thus, we can conclude that the molarity of a solution is 0.01162 M.

Suppose that a 10-mL sample of a solution is to be tested for I− ion by addition of 1 drop (0.2 mL) of 0.13 M Pb(NO3)2.
Liono4ka [1.6K]

The minimum number of grams of I that must be present is ; 0.01836 * 10⁻³ mol

<u>Given data : </u>

Volume of solution to be tested for I-ion = 10 mL

Volume of  Pb(NO₃)₂ = 0.2 mL

molarity of Pb(NO₃)₂ = 0.13 M

<h3>Determine the number of I that must be present </h3>

First step : calculate conc of PB²⁺ ions in the solution

conc of PB²⁺ ions =  ( molarity of Pb(NO₃)₂ * volume of  Pb(NO₃)₂ ) / ( total volume )

                              = ( 0.13 * 0.2 ) / ( 10 + 0.2 )

                              = ( 0.026 ) / ( 10.2 )  = 0.002549 M

Next step :<u> </u><u>determine the</u><u> molarity of  I</u>

using the dissociation reaction of PbI₂

PbI₂(s) ---> Pb²⁺ (aq)  + 2I (aq)

also;  Ksp = [ Pb²⁺ ] [ I ]²  ---- ( 1 )

From the question the given value of Ksp = 8.49 * 10⁻⁹

Therefore equation ( 1 ) becomes

8.49 * 10⁻⁹ = ( 0.002549 ) * [ I ]²

[ I ] = √ ( 8.49 * 10⁻⁹ ) / ( 0.002549 )

      = 0.0018 M

Final step :<u> Determine the minimum number of grams of I </u>

moles of I = molarity of I * total volume

                 = 0.0018 M * 10.2 mL

                 = 0.01836 * 10⁻³ mol

Hence we can conclude that The minimum number of grams of I that must be present is ; 0.01836 * 10⁻³ mol

Average atomic mass work
babymother [125]
Take 234/100 x 0.01
then 235/100 x 0.71
then 238/100 x 99.28
you divide by 100 because the abundance is given in percentage over 100
then add up all the values, you should get an answer of 237.97 rounded up is 238.
Final answer : 238
hope this helped :)

What is the total amount of matter in an ecosystem doing? always changing always increasing always decreasing remaining the same
Ilya [14]

Answer:

Remaining the same

Explanation:

By the Lavoisier's principle the matter can't be created nor destroyed, but always transformed.

It means that in an ecosystem, the matter, and also the energy, is not increasing and not decreasing, the total amount remains the same, but in different forms.
