First find the mass of <span>solute:
Molar mass KNO</span>₃ = <span>101.1032 g/mol
mass = Molarity * molar mass * volume
mass = 0.800 * 101.1032 * 2.5
mass = 202.2064 g of KNO</span>₃
<span>To prepare 2.5 L (0800 M) of KNO3 solution, must weigh 202.2064 g of salt, dissolve in a Beker, transfer with the help of a funnel of transfer to a volumetric flask, complete with water up to the mark, capping the balloon and finally shake the solution to mix.</span>
hope this helps!
Answer:
72.6 mL
Explanation:
A quick way to solve this titration problem when you have a monoprotic acid is to use the Dilution equation, M1V1=M2V2.
.589(x)=.821(52.1)
X=72.6 mL
Answer:
two electrons.
Explanation:
Helium-5, like all other helium isotopes, has two protons and two electrons. Its different from the others in the fact that it has three neutrons. It is one of the unstable isotopes, having a half-life of significantly less than a picosecond (a trillionth of a second). your welcome!!
Answer:
Benzene Hexachloride
Explanation:
BHC in benzene mean ''Benzene Hexachloride''.
<h2>B = Benzene</h2><h2>H + C = Hexachloride </h2>
As you can see, There are only two words and three letters. Even though it is one word, Hexa = H and Chloride = C
Neutrons are the other particles found in the nucleus. Neutrons are neither positively charged nor negatively charged. They are neutral.
