One atom of cesium has a mass of 132.9054 amu, and one mole of cesium has a mass of 132.9054 grams, so five moles of cesium has a mass of 664.527 grams.
Multiplying the mass of a particle (which can be an atom, molecule, etc.) by Avogadro's number (6.022x1023, the number of particles of a substance in 1 mole) will give you the mass of a mole of that particle, or molar mass, in grams. Avogadro's number is special because the molar mass of a substance will be the same number as its Atomic Mass, only in grams!

How many gram-moles in 320 grams of SO2?
To determine the number of gram-moles in 320 grams of SO2, you first need to find the molar mass of SO2, which is 64.07 g/mol. Then you divide the given mass (320 g) by the molar mass to get the number of moles. Therefore, 320 grams of SO2 is equivalent to 5 moles.

How many atoms are there in 0.575 grams cesium?
To find the number of atoms in 0.575 grams of cesium, you first need to convert grams to moles using the molar mass of cesium. Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in one mole of cesium. Multiply the number of moles by Avogadro's number to find the number of atoms in 0.575 grams of cesium.
How many moles of cesium chlorate must be decomposed to produce 2.7 moles of oxygen gas?
To find the moles of cesium chlorate needed to produce 2.7 moles of oxygen gas, use the balanced chemical equation for the decomposition of cesium chlorate: 2CsClO3 -> 2CsCl + 3O2 From the equation, it shows that 2 moles of cesium chlorate produce 3 moles of oxygen gas. Therefore, you will need (2/3) * 2.7 = 1.8 moles of cesium chlorate to produce 2.7 moles of oxygen gas.
How many moles are there in 5 grams of silicon dioxide?
To determine the number of moles in 5 grams of silicon dioxide (SiO2), you first need to calculate the molar mass of SiO2. The molar mass of SiO2 is 60.08 g/mol. Then, use the formula Moles = Mass / Molar mass to find that there are approximately 0.083 moles in 5 grams of SiO2.
How many moles are there in 5gram of sulphur?
