The number of grams in 2.65 mol of So2 is 2.65?
2.65moles * 64.1g = 169.6
Which of the following reactions shows that the formation of SO2 releases 296.8 kJ mol?
S(s) + O2(g) SO2(g) + 296.8 kJ
What is the percent of carbon by mass in C4H10O?
To find the mass of carbon as a percent of the molecule, you have to first know the mass of the whole molecule. This can be done with the atomic weights of the elements and multiplying them by the number of atoms in a single molecule of hexachlorophene (the given compound).Carbon: 12.0 g/mol × 13 = 156Hydrogen: 1.0 g/mol × 6 = 6.0Chlorine: 35.5 g/mol × 6 = 213Oxygen: 16.0 g/mol × 2 = 32.0C13H6Cl6O2 = 407 g/mol(Mass of carbon ÷ total mass) × 100 = % carbon by mass(156 ÷ 407) × 100 = 38.3% carbon
What is the molar mass of sodium oxalate?
molar mass is 318 g/mol (2X27)+3(2X12+4X16)=318g/mol
What is the formula mass of CS2?
Formular mass is the sum of the atomic mass' of the corresponding elements. C = 12.011 g/mol S = 32.06 g/mol 12.011 g/mol + 2(32.06 g/mol)= 76.131 g/mol Therefore, the formula mass of CS2 is 76.131 g/mol.
Which is the greatest mass of SO2 that can produced from 15.0 mol Cu2S?
The maximal mass is 30 moles sulfur dioxide.
What is the percentage mass of O in SO2?
Oxygen is 49.95% of the mass of SO2. The molecular weight is 48.06 g/mol and sulfur's molecular weight is 32.06 g/mol, so oxgyen must make up the other half of the compounds molecular weight.
What is the total number of molecules of SO2 in a 0.10 mole sample of So2?
.10 mol X (6.02X10 to the 23)/1 mole =6.02x 10 to the 22
How many SO2 molecules are in 1.75 mol of SO2?
1.75 moles SO2 x 6.02x10^23 molecules SO2/mole SO2 = 1.05x10^24 molecules
What is molecular weight of so2?
The relative atomic mass of sulfur is 32. And for oxygen, it is 16. Therefore the molecular weight of sulfur dioxide is 64 g/mol.
How many grams of NaCl would you have if you had 3.7 moles of NaCl?
Molar mass of Na = 22.9898g/mol Molar mass of Cl = 35.45g/mol Total molar mass = 58.4398g/mol 58.4398g * 3.7mol =216.22726g
The number of grams in 2.65 mol of So2 is 2.65?
2.65moles * 64.1g = 169.6
Which of the following reactions shows that the formation of SO2 releases 296.8 kJ mol?
S(s) + O2(g) SO2(g) + 296.8 kJ
How many O atoms in 1.25 mol of SO2?
1.51x10^24 atoms of O
What is the mass of 0.7891 mol of ferric oxide (Fe2O3)?
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
What is the mass of 0.7891 mol of ferric oxide?
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
