The correct answer is 0.04287 M
It is given that the rate constant of the reaction is 6.2 × 10⁻⁵ mol/L/s
Thus, as the rate of the reaction is in mol/L/s, it is a zero order reaction.
The initial concentration of a is 0.0500 M, and there is a need to find the concentration of a after 115 seconds. This can be done with the help of the equation:
[A]o -[A] = kt
[A] = [A]o - kt
= (0.0500 M) - (6.2 × 10⁻⁵) (115 s)
= 0.04287 M
Answer:
207.89g
Explanation:
The formula of the compound is:
Fe₂S₃
Find the molar mass of the compound;
Atomic mass of Fe = 55.845g/mol
S = 32.065g/mol
Now;
Molar mass of Fe₂S₃ = 2 (55.845) + 3 (32.065)
= 207.89g
