Q. How do you find the number of moles?
To find the number of moles in a sample, simply weigh it and divide the weight by the molecular weight. The quotient is equal to the number of moles. Example: How many moles are there in 300 grams of sodium bicarbonate? The molecular weight of sodium bicarbonate is 84 grams/mole.
Q. What is the mass of a mole?
The molar mass of a substance is the mass in grams of one mole of that substance. This mass is given by the atomic weight of the chemical unit that makes up that substance in atomic mass units (amu). For example, silver has an atomic weight of 107.8682 amu, so one mole of silver has a mass of 107.8682 grams.
Q. How many moles are in 125g of H2SO4?
The answer is 98.07848. We assume you are converting between grams H2SO4 and mole. You can view more details on each measurement unit: molecular weight of H2SO4 or mol This compound is also known as Sulfuric Acid. The SI base unit for amount of substance is the mole.
Q. How many moles are in 74 grams of KCl?
How many grams KCl in 1 mol? The answer is 74.5513. We assume you are converting between grams KCl and mole. You can view more details on each measurement unit: molecular weight of KCl or mol This compound is also known as Potassium Chloride.
Q. What is the mass of 5 moles of H2SO4?
490g
Q. How many grams are in 1.50 moles of KMnO4?
The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles KMnO4, or 158.033949 grams.
Q. What is the mass of 5 moles of hydrogen gas?
Answer: Hydrogen’s molar mass is 1.008 g/mol. Hydrogen gas’s formula is H2 meaning its composed of two hydrogens therefore its molar mass is 2.016 g/mol. 5 mol H2 x 2.016g/mol = 10.08 g.
Q. What is the formula of Sulphuric acid?
H₂SO₄

| Compound | Formula | % by Weight |
|---|---|---|
| Acetic acid, glacial | CH3COOH | 99.5 |
| Formic acid | HCOOH | 90 |
| Hydrochloric acid | HCl | 36 |
| Nitric acid | HNO3 | 71 |
Q. What is the pH of sulfuric acid?

| Acid | Normality | pH |
|---|---|---|
| Sulfuric | N | 0.3 |
| Sulfuric | 0.1 N | 1.2 |
| Sulfuric | 0.01 N | 2.1 |
| Sulfurous | 0.1 N | 1.5 |
Q. What is the formula for phosphorous acid?
H3PO3
Q. What is the name of H 3 PO 3?
Phosphorous acid
Q. What is the strongest acid on earth?
Fluoroantimonic acid
Q. What is the pH of 2% sulfuric acid?
1.01
Q. What is the pH of 1M sulfuric acid?
0
Q. What is the lowest pH acid?
Which acid got lowest pH? – Quora. Fluoroantimonic acid can be as low as -25 on the pH scale. That’s 10^19 times stronger than sulfuric acid.
Q. How do you calculate pH?
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H3O+].
Q. How much acid do I add to lower pH?
In other words, add acid until the alkalinity reaches about 90 to 100 ppm. Then aerate until the pH rises to 7.4 to 7.6. The main rule to keep in mind is that it takes 25.6 oz. of full-strength muriatic acid (31.45 percent hydrochloric acid) to lower the total alkalinity by 10 ppm in 10,000 gallons.
