What do you do when you have a mixed number in percentage base and rate?
What you need to do depends on what you wish to achieve.
When to use avogadros number?
When converting the mols measurement into atomic weight (or vice-versa). Since there are 6.02x10^26 atoms in a mol. There are some keywords you can look for to determine whether or not you need to use Avogadro's number. Look for the keywords ions, molecules, moles (IF grams [g] to moles), and formula units in the question. If the question is asking for any of these terms or involves any of those terms, Avogadro's number will be necessary to use.
What is 19 over 24 as a mixed number?
Since the numerator is smaller than the denominator, there is no need to change this fraction into a mixed number.
If you multiply or divide both sides of an inquality by a negative number you need to the inquality sign?
flip the sign, meaning change < to > or > to <

Converting moles into atoms?
In order to convert you would need to multiply the number of moles by Avogadro's number (6.022 x 1023). And that would give you atoms (or molecules or ions).
The relationship between the moles of solute dissolved in a solution and the number of moles of particles in solution is called the?
I need this too. I've read that it may be the Van't Hoff factor.
How do you convert 1.70 g gas at 271.4 Kelvin to moles?
I would need to know what kind of gas you're talking about. Once you know that, you can use the periodic table to do a mass-mole conversion to get the number of moles. The number moles won't change as temperature changes, but its volume would change, as per the gas laws.
What information do you need to determine how a change in pressure will affect the equilibrium of a reaction?
The total number of moles of gas on each side of the reaction.
How do you find the number of moles that will react with 5 grams of butane?
We need to know the number of moles of WHAT is to react with the butane to provide you with an answer.
How do you find the amount of precipitate in a saturated solution?
first you need to know the number of liters and moles and the equation. you do someting then multiply the liters times the moles. first you need to know the number of liters and moles and the equation. you do someting then multiply the liters times the moles.
What is 4.49x1023 to moles?
I assume you mean atoms to moles. You need to divide by avagadro's number, 6.022x10^23. 4.49x10^23/6.022x10^23 is 0.7456 moles.
How do you convert grams to moles using avogadros number?
You don't need to use Avogadro's number, you need the mass of the molecule in atomic units. Mass / molecular mass = moles eg for water, 36 grams / 18 atomic units = 2 moles
How many grams are in 6.60 moles of ZnO?
You need the molar solution to get the number of moles present in 6.52g of Zinc Sulfate.
When two elements are chemically bonded why doesnt the number of particles change?
Because each set of atoms need each other to retain electron stability.
How many moles of sulfuric acid are present in 0.550 L of a 0.150 M sulfuric acid solution?
.150 M is the molarity of the solution, which is the number of moles per liter. So all you need to do is multiply the molarity by the number of liters. So .150 moles/liter x .550 L = .0825 moles
How many moles are in 11.9 moles of chromium?
For this you need the Atomic Mass of Cr. Take the number of moles and multiply it by the Atomic Mass. Divide by one mole for units to cancel.11.9 moles Cr × (52.0 grams) =618.8 grams Cr
