Molarity is defined as the number of moles of solute in volume of 1 L solution.
the molarity of KOH solution to be prepared is 0.500 M
the volume of solution to be prepared is 250 mL
the number of KOH moles in 1 L - 0.500 mol
therefore number of KOH moles in 250 mL - 0.500 mol/L x 0.250 L = 0.125 mol
Mass of KOH in 0.125 mol - 0.125 mol x 56.10 g/mol = 7.01 g
The mass of KOH required to make the solution is therefore 7.01 g
Answer:
Explanation: Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products.
The ion between it is a Ionic bond
There are 5.35 × 10²⁴ atoms in 8.89 moles of Helium.
<u>Explanation:</u>
Given that number of moles of Helium = 8.89 moles
Moles and Avogadro's number are related to each other by multiplying those two we can convert moles into atoms, molecules and Particles .
We have to convert the moles into atoms by multiplying the molar amount by Avogadro's number as,
Number of atoms = 8.89 × 6.022 × 10²³ atoms
= 5.35 × 10²⁴ atoms
So there are 5.35 × 10²⁴ atoms in 8.89 moles of Helium.
<span>This would have a product of gulitol. When the double-bond between the carbon and the oxygen atoms on the end of the D-gulose chain breaks and becomes a single hydroxide bond with two hydrogen bonds emanating from the oxygen, a sugar alcohol forms.</span>
