moles of acid = moles base = moles base/liter x liters of base used
6.022 x 1023 formula units of K2O are equal to one mole of K2O.
0.688 moles*6.02x1023=4.14x1023 Formula units
No amount of sodium sulphate can be formed from sodium hydroxide alone, because sodium sulfate contains sulfur and sodium hydroxide does not. By neutralization with sulphuric acid, one formula unit of sodium sulphate can be formed from two moles of sodium hydroxide, according to the equation 2 NaOH + H2SO4 -> Na2SO4 + 2 H2O.
The answer is 5,978 moles.
If there is no number in front of the formula, the number of moles is understood to be one.
2,888.10e15 molecules of AgNO3 equal 0,48.10e-8 moles.
42.394 grams.
6.022 x 1023 formula units of K2O are equal to one mole of K2O.
Molarity is a concentration unit of solutions, pure benzene is not a solution so this term is meaningless for a pure liquid. In other words: Molarity of a solution is a numerical way of saying exactly how much solute is dissolved in a solvent .Molarity is equal to the moles of solute divided by the liters of solution. Molarity of a solution can be calculated by using the following formula: M= moles of solute/liters of solution
0.688 moles*6.02x1023=4.14x1023 Formula units
Since both the acid and the base have equivalent weights equal to their formula weights, 2 moles of KOH are needed to neutralize 2 moles of nitric acid.
No amount of sodium sulphate can be formed from sodium hydroxide alone, because sodium sulfate contains sulfur and sodium hydroxide does not. By neutralization with sulphuric acid, one formula unit of sodium sulphate can be formed from two moles of sodium hydroxide, according to the equation 2 NaOH + H2SO4 -> Na2SO4 + 2 H2O.
2,5 moles of silver is equal to 269,6705 g.
The answer is 3,33 moles.
The answer is 5,978 moles.
The chemical formula of sodium chloride is NaCl; formula is not dependent from the number of moles. Because the molecular mass of NaCl is 57,958 622 382, the mass of 20 moles is 1159,172 447 64.
The formula is: number of moles = g Be/9,012.
