For the isotope francium-223 this mass is 167,25 g.
Multiply the number of moles by the molecular weight.
For this you need the atomic mass of Fe. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel..410 grams Fe / (55.9 grams) = .00733 moles Fe
first you must have a mass in mind. eg 345 grams of Carbon divided the mass by the molar weight of the particular substance. In the case of Carbon 12 grams/mole 345 grams/12 grams/mole = 28.75 moles
There are 0.75 moles in it.You have to devide 12 by molecular mass
For this you need the atomic mass of Na. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.11.5 grams Na / (23.0 grams) = .500 moles Na
To convert grams to moles, you need to know the molar mass of the substance. Divide the given mass in grams by the molar mass to find the number of moles. This calculation is done using the formula: moles = grams / molar mass.
To find the mass of 1.54 moles of H2O, you can use the molar mass of water. The molar mass of H2O is 18.015 grams/mol. Therefore, the mass of 1.54 moles of H2O would be 1.54 moles * 18.015 grams/mol = approximately 27.75 grams.
Mass in grams = no of moles x molecular mass. So, mass in grams = 5.2x 56 = 291.2g
number of moles = mass of the material/molar mass
all you have to do to fine the moles of any element is divide the given grams by the molar mass (which you can find on a periodic table of elements) Likewise, if you need to find the grams, just multiply the number of moles by molar mass. moles = grams/molar mass grams = moles x molar mass your equation should look like this: moles = 89.0 / 17.0 moles = .471
To convert moles to grams, you use the molar mass of calcium. The molar mass of calcium is approximately 40.08 g/mol. Therefore, 1.3 moles of calcium would be 1.3 moles x 40.08 g/mol = 52.10 grams of calcium.
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
The molar mass of gold is approximately 197 grams/mol. To convert moles to grams, you multiply the number of moles by the molar mass. Therefore, 2.8 moles of gold would be approximately 2.8 * 197 = 551.6 grams.
To find the number of moles in 57 grams of Xenon, divide the given mass (in grams) by the molar mass of Xenon. The molar mass of Xenon is 131.3 grams/mol. Therefore, 57 grams of Xenon is equal to 0.434 moles (57/131.3).
To calculate the mass in grams of sodium sulfate, we need to know the number of moles. Once we have the number of moles, we can multiply it by the molar mass to find the mass in grams. For example, if we have 2 moles of sodium sulfate, the mass would be 2 moles * 141.98 grams/mole = 283.96 grams.
The molar mass of hydrogen peroxide (H2O2) is 34.01 g/mol. To find the mass of 1.50 moles, you would multiply the number of moles by the molar mass: 1.50 moles * 34.01 g/mol = 51.015 grams. So, the mass of 1.50 moles of hydrogen peroxide is 51.015 grams.
For this you need the atomic (molecular) mass of NO. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NO=30.0 grams6.64 grams NO / (30.0 grams)= .221 moles NO
