The molar mass of potassium hydroxide (KOH) is 56.11 g/mol. Therefore, 1 mole of potassium hydroxide weighs 56.11 grams.
1 mole of hydrochloric acid reacts with 1 mole of potassium hydroxide in a 1:1 ratio. Therefore, 0.100 mole of hydrochloric acid would require 0.100 mole of potassium hydroxide to completely neutralize it.
Actually there are two possibillities:K2SO4, potassium sulfate, when 1 mole sulfuric acid is added to 2 moles potassium hydroxide 2 KOH + H2SO4 ------> K2SO4 + 2 H2OorKHSO4, potassium hydrogen sulfate (-bisulfate), when 1 mole sulfuric acid is added to 1 mole potassium hydroxide 1 KOH + H2SO4 ------> KHSO4 + H2O
60 g NaOH x 1 mole NaOH/40 g NaOH = 1.5 moles NaOH
2 KOH + H2CO3 = 2 H2O + K2CO3
Sodium hydroxide (chemical composition NaOH) has an atomic mass of 40 amu which is also 40 grams/mole
The molar mass of sodium hydroxide (NaOH) is approximately 40 grams per mole. Therefore, a 6.94 mole sample of sodium hydroxide would contain approximately 278 grams (6.94 moles x 40 grams/mole).
1 mole of hydrochloric acid reacts with 1 mole of potassium hydroxide in a 1:1 ratio. Therefore, 0.100 mole of hydrochloric acid would require 0.100 mole of potassium hydroxide to completely neutralize it.
the molar mass of potasium hydroxide is 56 g/mole
Actually there are two possibillities:K2SO4, potassium sulfate, when 1 mole sulfuric acid is added to 2 moles potassium hydroxide 2 KOH + H2SO4 ------> K2SO4 + 2 H2OorKHSO4, potassium hydrogen sulfate (-bisulfate), when 1 mole sulfuric acid is added to 1 mole potassium hydroxide 1 KOH + H2SO4 ------> KHSO4 + H2O
It depends on whether it is iron (II) hydroxide or iron (III) hydroxide.
60 g NaOH x 1 mole NaOH/40 g NaOH = 1.5 moles NaOH
2 KOH + H2CO3 = 2 H2O + K2CO3
Sodium hydroxide (chemical composition NaOH) has an atomic mass of 40 amu which is also 40 grams/mole
Every atom of potassium has a mass of 39 amu. Each mole of potassium has a mass of 39 grams.
There are 39.0983 grams in one mole of K (potassium). a mole is a number. you cannot ask how many moles are in potassium. but you may ask how many moles of a certain substance are in potassium.
The atomic mass of Potassium is 39 and that of Sulfur 32. The formula for Potassium Sulfide is K2S therefore the molecular weight of Potassium Sulfide is (39 * 2) + 32 = 110. Therefore one mole of Potassium Sulfide weighs 110 grams. Therefore 3.3 moles of Potassium Sulfide weigh 110 * 3.3 = 363 grams.
Normal plasma potassium is 3.5 to 5.0 mmol/L (millimole per liter). Molecular weight expressed in grams is a mole. In case of potassium, which has a molecular weight of 39; 39 grams of it is 1 mole. Thus 39 mg of potassium is one milli mole (mmol). Their levels are usually expressed in milli moles due to many reasons. One reason is that, their numbers have important influences on osmotic activity, and simple weights in grams fail to convey this fact.
