Answer:
57 grams of H3PO4
Explanation:
M= moles/ liters
convert mL to L
234 mL x 1L/1000mL = 0.234L
Rearrange the Molarity formula to solve for moles.
moles= MxL
moles= 2.5M x 0.234L
moles= 0.585 mol
Use the molar mass of H3PO4 to get to grams
0.585 mol x 97.994 grams/1 mol = 57.326 grams of H3PO4
round to two sig figs for 57 grams
Answer:
is the rate constant for this reaction.
It will take 
to concentration to reach 12.5% of its original value.
Explanation:
A decomposition reaction follows first order kinetics:
Half life of the reaction = 
Rate constant of the reaction = k
For first order reaction, half life and rate constant are linked with an expression :
is the rate constant for this reaction.
Initial concentration of reactant =![[A_o]](https://tex.z-dn.net/?f=%5BA_o%5D)
= x
Final concentration of reactant after time t =![[A]](https://tex.z-dn.net/?f=%5BA%5D)
= 12.5% of x = 0.125x
The integrated law of first order reaction :
![[A]=[A_o]\times e^{-kt}](https://tex.z-dn.net/?f=%5BA%5D%3D%5BA_o%5D%5Ctimes%20e%5E%7B-kt%7D)
t = 1,734.31 years =
It will take to concentration to reach 12.5% of its original value.
