Answer:
1.43*10 to the power of -10
Explanation:
Since 1.43*10 to the power of -10 is nothing else but
1.43/10¹⁰ which is equal to the number in the question
It is not 10¹⁰ because it will increase the number of zeros to the right
but we need to increase it towards the left
Hope this helps

2A → B + C
First trial ;
[A] = x , Rate of the reaction = R
Rate law of the reaction can be written as:
..[1]
Second trial ;
[A] = 3x , Rate of the reaction = R' = 9R
Rate law of the reaction can be written as:
..[2]
[1] ÷ [2]
a = 2
Rate of the reaction :
The order of the reaction is 2. This is because in the rate law expression the the power of the concentration of reactant A id 2.
Mass per volume percent is simply calculated by getting the ratio of the mass in g of solute and the volume in mL of the solution multiplied by 100 percent. In the problem, we are given all the required values. Calculation is as follows:
%w/v = 140 / 1590 x 100 = 8.81%
