Answer:
In a nutshell, diet refers to all the food that you consume through the day, on a regular basis. Nutrition, on the other hand, refers to the fuel that your body requires to function optimally and maintain good health. It refers to the right mix of nutrients.
Explanation:
Mass of electrons are not included when calculating the atomic mass of element. Atomic mass of the element is equal to proton + neurons. Example the the mass number of Nitrogen can be calculated as 7 protons + 7 neutrons to give 14 . thus nitrogen has a mass number of 14
Yes, because CO2 is carbon dioxide, and carbon dioxide contains molecules.
Since the atomic number of calcium is 20. The number of protons is also 20.
Answer:
Explanation:
Hello!
In this case, since the molarity of a solution is computed by dividing the moles of solute by the volume of solution in liters, we first need to compute the moles of solute knowing that the molar mass of calcium hydroxide is 74.1 g/mol as follows:
Next, since the 100-mL solution is also expressed in liters by 0.100 L, we directly compute the molarity as shown below:
Which is expressed in molar units that are mol/L.
Best regards!
