Answer:
0.500 L
Explanation:
concentration = number of moles / volume
volume = number of moles / concentration
Answer:
Reaction of water with K₂O produce base.
Explanation:
Reaction of water with K₂O:
K₂O + H₂O → 2KOH
when potassium oxide react with water it produces potassium hydroxide which is base.
Reaction of water with carbondioxide:
When carbondioxide react with water it produces carbonic acid.
CO₂ + H₂O → H₂CO
Carbonic acid is a weak acid and dissociate to gives H⁺ ions. It is aslightly acidic solution and convert into hydrocarbonate ions.
H₂CO₃ → H⁺ + HCO⁻₃
HCO⁻₃ → H⁺ + CO₃⁻²
Reaction of water with NO₂:
3NO₂ + H₂O → 2HNO₃ + NO
Nitrogen dioxide react with water and produce nitric acid and nitrogen monoxide.
Reaction of water with SO₂:
SO₂ + H₂O → H₂SO₃
When sulfur dioxide react with water it gives sulfurous acid.
Answer:
98.08 g/mol
Explanation:
In order to find the molar mass of a substance, you add together the mass of the total number of moles of each element in the substance.
H2SO4 contains:
2 mol H (1.01 g/mol)
1 mol S (32.06 g/mol)
4 mol O (16.00 g/mol)
2(1.01) + 32.06 + 4(16.00) = 98.09 g/mol
Para encontrar la masa molar de una sustancia, suma la masa del número total de moles de cada elemento de la sustancia.
H2SO4 contiene:
2 mol H (1.01 g/mol)
1 mol S (32.06 g/mol)
4 mol O (16.00 g/mol)
2(1.01) + 32.06 + 4(16.00) = 98.09 g/mol
