Answer:
0.30 M
Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t = ?
is the initial concentration = 1.36 M
k is the rate constant = 0.208 s⁻¹
t = 7.30 seconds
So,
Why would you ask a question if you didnt have a question?
Just get someone to report it, and itll be deleted
Answer:moles = no. of molecules / Avogadro's number
= 2.26 x 10^33 / 6.022 x 10^23
= 3752906011
Round to significant figures which is 3 = 3.75 x 10^9 mol
Explanation:
The formula for finding how many moles of a substance when given the amount of molecules is: moles = number of molecules / Avogadro's number
