Answer : The correct option is, (3) titration
Explanation :
Titration : It is a laboratory process where we have to use the volume of a solution of known concentration to determine the concentration of unknown solution.
Distillation : It is a process in which we used to separate a pure liquid from the mixture of the liquids based on the different boiling points.
Fermentation : It is a chemical process in which the the bacteria, an organism or yeast converts the carbohydrate into an alcohol or an acid.
Transmutation : It is a process in which the nucleus of a chemical elements changes into another.
Hence, the correct option is, (3) titration
Answer:
(a) 0.0345 g/cm^3
Explanation:
<u>Given:</u>
Edge length of cube (a) = 0.750 m
Mass = 14.56 kg
<u>To determine:</u>
The density of the cube
<u>Calculation:</u>
Unit conversions:
1000 g = 1 kg
Therefore, the mass of cube in g = 14.56*10³ g
10⁶ cm³ = 1 m³
Therefore the volume of the cube in cm³=0.422*10⁶cm³
Based on equation (1)
Answer:
2 molecules of water represents 3.32 x 10^-24 moles of water.
Explanation:
To find the solution to this problem, you have to use the concept of Avogadro´s number, that is in 1 mol of any element o compound there are 6.022 x 10^23 molecules. Then,
1 mol H2O ------------- 6.022 x 10^23 molecules
x= 3.32 x 10^-24 ---- 2 molecules.
2 molecules of water represents 3.32 x 10^-24 moles of water.
Answer:
asexual reproduction produces offspring with the same Gene's
It is B, and also for a moment I didn't understand that 4.69 x 10^22. I almost did this whole problem wrong.
