Explanation:
There are several ways of expressing concentration of solution. Few of them are listed below
1) mass percentage
2) volume percentage
3) Molarity
4) Normality
5) Molality
In most of the drugs, concentration is expressed either in terms of mass percentage or volume percentage. For, solid in liquid type systems, mass percentage is convenient way of expressing concentration, while for liquid in liquid type solutions, expressing concentration in terms of volume percentage is preferred. Present system is an example of liquid in liquid type solution
Here, concentration of H2O2 is given antiseptic = 3.0 % v/v
It implies that, 3ml H2O2 is present in 100 ml of solution
Thus, 400 ml of solution would contain 4 X 3 = 12 ml H2O2
Protons .because electron has negative charge and proton has positive charge.
Ga2(CO3)3 is the formula.
Answer:
The answer is
<h2>4.69 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass of wood = 4.6 g
density = 0.98 g/mL
It's volume is

We have the final answer as
<h3>4.69 mL</h3>
Hope this helps you
