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 <
What is the absolute value of l 10 - 5 l?

Converting moles into atoms?
To convert moles into atoms, you need to use Avogadro's number, which is 6.022 x 10^23 atoms per mole. Simply multiply the number of moles by Avogadro's number to get the number of atoms. For example, if you have 2 moles of a substance, you would multiply 2 moles by 6.022 x 10^23 atoms/mole to get 1.2044 x 10^24 atoms. This conversion is important in chemistry when working with large quantities of atoms.
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 particle to mole?
You need the initial mole that you want to turn into particle Use that multiply by the advogadro number (6.022x10*23 ) The particle is a big term for things like atoms, or anything for the name of something that add up to a mole. 2 mole of hydrogen X 6.022x10*23 particles / mole = the # of particles
How many moles of specified particles are present in a sample of N'O if each sample weighs 7.00 g?
To calculate the number of moles of particles present in a sample, you need to divide the sample's mass by the molar mass of the particles. If you specify the particles as N'O, you should provide the molar mass of N'O for an accurate calculation.
How many particles are in 7.8g of NaCl?
To calculate the number of particles in 7.8g of NaCl, you first need to determine the number of moles using the molar mass of NaCl (58.44 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 particles/mol) to find the number of particles.
How many moles of iodine molecules correspond to 1.80x1024 molecules of I2?
To find the number of moles, you first need to determine the molar quantity of iodine molecules based on Avogadro's number. Since 1 mole contains 6.022 x 10^23 molecules, you would divide 1.80 x 10^24 molecules by Avogadro's number to get the number of moles.
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.
How do you convert grams to moles using avogadros number?
To convert grams to moles, you divide the given mass in grams by the molar mass of the substance in grams per mole, which is obtained from the periodic table. This calculation gives you the number of moles present. Avogadro's number (6.022 x 10^23) is used to convert moles to individual particles or entities like atoms or molecules.
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 many representative particles are in 1.45 g of a molecular compound with a molar mass of 237 g?
There are 6.02 x 10^23 representative particles (molecules) in 1 mole of a substance. To find the number of representative particles in 1.45 g of a compound with a molar mass of 237 g, you first need to determine the number of moles in 1.45 g of the compound using the formula: moles = mass / molar mass. Then, multiply the number of moles by Avogadro's number to find the number of representative particles.
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.
