Why does h2o have a lower relative molecular mass than cs2?
H₂O (water) has a lower relative molecular mass than CS₂ (carbon disulfide) because the molecular mass of H₂O is approximately 18 g/mol (composed of two hydrogen atoms and one oxygen atom), while CS₂ has a molecular mass of about 76 g/mol (comprising one carbon atom and two sulfur atoms). The difference in the number and mass of the constituent atoms results in H₂O having a significantly lower molecular weight compared to CS₂.
What ions would be most likely to form?
Atoms of alkaline metals: Rb, Cs, Fr, K, Na, Li. They have a low ionization potential. This potential is expressed in kJ/mol - molar ionization energy and is different for the first, second, third...n electron.
What is mass of 5.000 mols of cesium and the atomic mass 132.9?
The atomic mass is the mass in grams of one mole of the atoms concerned. Thus, 5 X 132.9 = 664.5 grams.
How many moles of C are contained in 595 kg of C?
Cs = 132.91 g/mol 1 kg = 1000g 595kg x (1000g/1kg) x (1mol/132.91g) = 4476.713566 = 4.48 x 10^3 mol Cs
The average atomic mass of the element cesium is approximately 133 you What is the mass of 3.00 mol of cesium?
The molar mass of cesium (Cs) is approximately 133 g/mol. Therefore, the mass of 3.00 mol of cesium would be 3.00 mol x 133 g/mol = 399 g.
How many Cs atoms are there in a 53.7 gram sample of Cs?
This is a two-step calculation. First convert grams Cs to moles Cs. Then convert moles Cs to atoms Cs.The atomic weight of cesium is 133 g/mol1. To convert grams to moles:moles Cs= 53.7 g Cs1 mol = 0.404 mol Cs133 gMultiply by moles per gram. Grams cancel out.2. To convert moles to atoms:atoms Cs = 0.404 mol Cs6.02 x 1023 atoms = 2.43E+23 atoms CsmolMultiply by atoms/mole. Moles cancel out.

What is the molar mass of CsC2?
MM Cs = 132.91 g/mol MM C = 12.011 g/mol MM CsC2 = 156.93 g/mol
What is the molecular formula of a compound containing 89 percent cesium Cs and 11 percent oxygen O with a molar mass equals 298 gmol?
The compound contains 1 cesium atom (Cs) and 1 oxygen atom (O). The molar mass of cesium is about 133.0 g/mol and oxygen is about 16.0 g/mol. Calculating the molar mass of Cs: (0.89 * 133.0 g/mol) = 118.37 g/mol Calculating the molar mass of O: (0.11 * 16.0 g/mol) = 1.76 g/mol Adding the molar masses together: 118.37 g/mol + 1.76 g/mol = 120.13 g/mol Thus, the molecular formula is CsO.
What is the mass of 3.00 mol of cesium?
The molar mass of cesium (Cs) is approximately 132.91 g/mol. Therefore, the mass of 3.00 mol of cesium would be 3.00 mol x 132.91 g/mol = 398.73 g.

How many moles of C are contained in 595 kg of C?
Cs = 132.91 g/mol 1 kg = 1000g 595kg x (1000g/1kg) x (1mol/132.91g) = 4476.713566 = 4.48 x 10^3 mol Cs
How many atoms are in 1.55 moles of Cs?
One mole of any mono-atomic element contains (by definition) 6.022*10+23 atoms. please calculate from there by multiplying - 9,334.1023 atoms.
How many F atoms are needed to occupy the same volume as a Cs atom?
Since the volume of an atom is determined by the radius of its electron cloud, we can use the atomic radius to approximate the volume each atom occupies. The atomic radius of Cs is larger than that of F, so more F atoms would be needed to occupy the same volume as one Cs atom. Approximately 9 F atoms are needed to occupy the same volume as one Cs atom.
