Dilution law is given as:
(1)
where, = molarity of initial concentrated solution.
= volume of initial concentrated solution.
= molarity of final diluted solution.
tex]V_{2}[/tex] = volume of final diluted solution.
Volume of initial concentrated solution of = 100.0 mL
Molarity of initial concentrated solution of = 5.50 M
Volume of final diluted solution of = 0.950 M
Put the values in formula (1),
Hence, final diluted volume of the solution is .
Answer:
its mass
its temperature
Explanation:
The heat capacity of a body is the amount of heat needed to raise that temperature of a body by 1k or 1°C.
It is expresses as:
H = m c Ф
where m is the mass of the body
c is the specific heat of the body
Ф is the temperature change of the body
Specific heat capacity is that heat content needed to raise the temperature of a unit mass of a substance by 1k or 1°C
Heat capacity is also known as heat content;
To solve the problem:
since H = m c Ф
we make the unknown c the subject of the expression;
c = = H / mФ
So to obtain the specific heat capacity, divided the heat capacity by mass and its temperature change.

Explanation:
Hello there!
In this case, according to the given combustion reaction of octane, it is possible for us to perform the stoichiometric method in order to calculate the mass of octane that is required to consume 300.0 g of oxygen by considering the 2:25 mole ratio, and the molar masses of 114.22 g/mol and 32.00 g/mol respectively:
