Answer:
The answer is
<h2>11.25 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
From the question
mass = 45 g
volume = 4 mL
Substitute the values into the above formula and solve for the density
We have
We have the final answer as
<h3>11.25 g/mL</h3>Hope this helps you
Answer: Rate of decomposition of acetaldehyde in a solution is
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
For a reaction :
k= rate constant
x = order of the reaction = 2
Thus rate of decomposition of acetaldehyde in a solution is
