The theoretical yield of a reaction is 5.00 moles of potassium permanganate . If the reaction actually produces 616.2 g KMnO₄ , the percent yield of the reaction is 78 %.
given that :
the theoretical yield of the reaction = 5 mol
mass of the potassium permanganate = 616.2 g
molar mass of the potassium permanganate = 158 g /mol
moles of the KMnO₄ = mass / molar mass
= 616.2 / 158
= 3.9 moles
the percent yield = ( experimental yield / theoretical yield ) × 100 %
= ( 3.9 / 5 ) ×100 %
= 78 %

What volume of 0.75 M H₂SO4 is required to neutralize 25.0
mL of 0.427 M KOH?
A volume of 0.02845 L is required to neutralize this acid-base reaction.
To neutralize an acid with a base, you need to react with equal molar amounts of the two. The balanced chemical equation for the neutralization of sulfuric acid (H₂SO₄) with potassium hydroxide (KOH) is as follows:
H₂SO₄ + 2 KOH → K₂SO₄ + 2 H₂O
The molarity of a solution is a measure of the number of moles of solute per liter of solvent. To find out how many moles of H₂SO₄ you need to neutralize 25.0 mL of 0.427 M KOH, you first need to convert the volume of KOH to liters, using the conversion factor 1 L/1000 mL.
25.0 mL KOH × (1 L/1000 mL) = 0.025 L KOH
Then, use the molarity of the KOH solution to find out how many moles of KOH you have:
0.427 M KOH × 0.025 L KOH = 0.010675 moles KOH
Since the balanced chemical equation shows that 1 mole of H₂SO₄ reacts with 2 moles of KOH, you need twice the number of moles of KOH, or 0.010675 moles × 2 = 0.02135 moles H₂SO₄.
Finally, use the molarity of the H₂SO₄ solution to find out how much volume you need:
(0.02135 moles H₂SO₄) ÷ (0.75 M H₂SO₄) = 0.02845 L H₂SO₄
So you need a volume of 0.02845 L of 0.75 M H₂SO₄ to neutralize 25.0 mL of 0.427 M KOH. This is equivalent to 28.45 mL of 0.75 M H₂SO₄.

O 3.4 mol H₂SO4
O 6.8 mol H₂SO4
O 10.2 mol H₂SO4
O 13.6 mol H₂SO4
3.4 mole of H₂SO₄ moles of sulfuric acid (H₂SO4) are needed to react completely with 6.8 moles of lithium hydroxide.
How many moles of sulfuric acid (H₂SO4) are needed ?
Based on the reaction’s stoichiometry: 2 LiOH + H2SO4 Li2SO4 + 2 H2O
It is obvious that when 2.0 moles of LiOH react with 1.0 mole of H2SO4, 1.0 mole of Li2SO4 and 2.0 moles of H2O are produced.
Making use of cross multiplication:
1.0 mole of H2SO4 totally interacts with LiOH (2.0 moles)
2.0 mole of H2SO4 is required to totally react with 6.8 mole of LiOH.
The mole of H2SO4 = (1.0 x 6.8) / (2.0) = 3.4 mole of H2SO4.
One mole of H2SO4 has an atomic mass of 98 grams. So 98 grams of H2SO4 comprises one mole of H2SO4 molecule, or seven moles of atoms.

What can be found in the box on a periodic table?
In the box on a periodic table we can find its atomic number, symbol, average atomic mass, and (sometimes) name of the element.
By the 20th century, it was clear that atomic numbers, not atomic masses, were involved in the periodic relationship. The periodic law, a more recent formulation of this relationship, states that an element's properties are a periodic function of its atomic number.
The elements are arranged in a modern periodic table in increasing order of their atomic numbers, and atoms with comparable properties are grouped in the same vertical column (Figure below). With its atomic number, symbol, average atomic mass, and (sometimes) name, each box represents an element. The elements are grouped in 18 vertical columns called groups and seven horizontal rows known as periods or series.
Each column's header lists the names of its groups. Roman numerals and capital letters have traditionally been used on labels in the United States. The IUPAC advises using the digits 1 through 18, and these labels are more widely used. Parts of two of the rows, totaling 14 columns, are typically written below the table's main body in order for it to fit on a single page.
