To solve multiply the mL by the mg/ml so 375*40=15000mg
The reaction is given as follows:
The plot of ln[cyclopropane] verses t is linear with slope .
The plot for ln[cyclopropane] verses t is linear for first order reaction (as in the diagram attached). The integrated rate law equation is as follows:
Here, k is rate constant, t is time of the reaction, is concentration of reactant at time t and is initial concentration of reactant.
Taking ln both sides,
Comparing with equation for linear graph, y=mx+c
Thus, slope =-k
Or, .
Therefore, order of the reaction is first and rate constant is .
Hello,
Here is your answer:
The proper answer to this question is "Deforestation".
Here is how:

Answer:
126g
Explanation:
Data obtained from the question include:
Mole of Fe = 2.5moles
Molar Mass of Fe = 56g/mol
Mass of Fe =?
Number of mole = Mass/Molar Mass
Mass = number of mole x molar Mass
Mass of Fe = 2.25 x 56
Mass of Fe = 126g
Therefore, the mass in 2.25mol of Fe is 126g
From,
RAM=element×its relative abudance/total abudance
=((107×13)+(12×109))/25
The answer is=107.96
