Answer:
A) 6.00 mol.
B) 0.375 L or 375 mL
C) 6.00 M
Explanation:
Hello,
A) In this case, from the definition of molarity, we compute the moles for the given volume and concentration:
B) In this case, from the stock solution, the required volume is:
C) In this case, we apply the following formula for dilution process:
Thus, solving for the final molarity, we obtain:
Regards.
Assuming that the reaction from A and C to AC5 is only
one-step (or an elementary reaction) with a balanced chemical reaction of:
<span>A + 5 C ---> AC5 </span>
Therefore the formation constant can be easily calculated
using the following formula for formation constant:
Kf = product of products concentrations / product of reactants
concentration
<span>Kf = [AC5] / [A] [C]^5 </span>
---> Any coefficient from the balanced chemical
reaction becomes a power in the formula
Substituting the given values into the equation:
Kf = 0.100 M / (0.100 M) (0.0110 M)^5
Kf = 6,209,213,231
or in simpler terms
<span>Kf = 6.21 * 10^9 (ANSWER)</span>
1/2 of the original parent has decayed, thus one half- life has passed, and the rock is 1.3 billion = 1300 million years old
<span> F = ma = 40kg * 10m/s^2 = 400 kg-m/s^2 = 400N</span>
