The moles can be defined as the mass of the substance with respect to molar mass. The moles of potassium nitrate is 1 mol.
<h3>How to calculate moles of a substance?</h3>
The moles of a compound can be calculated from:
The molarity can be defined as the moles of solute in a liter of solution.
The molarity can be expressed as:
The molarity of potassium nitrate solution is 2 M, and the volume is 500 mL.
The moles of potassium nitrate is given as:
The moles of potassium nitrate in 2 M, 500 mL solution are 1 mol.

An imaginary line joining a planet and the sun sweeps out an equal area of space in equal amounts of time. Thus, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.
Answer: Assuming the question: 3.54 ml (3 sig figs)
Explanation:
I don't see a question, but will assume it is "What volume is needed to obtain 26.5 grams?
If so:
(26.5 g)/(7.48 ml) = 3.54 ml (3 sig figs)
<span>In 5.70 mol of Hafnium there are 34,326 208 203*10^23 atoms.</span>
Answer and Explanation:
The water is a polar solvent which dissolves into the LiBr molecules and converts into 
and 
ions far from the solid also into the solution, when they are hydrated.
Now, the complete words are as given below:-
The 
and 
ions at the surface of the solid are pulled into the solution by the polar water molecules, where the hydration process surrounds separate ions with water molecules.
