Chemistry
1 answer:
Andrei [34K]2 years ago
6 0

The molar mass of SnO is  134.71 g/mol .

Molar mass of SnO is calculated as follows ,

  • Make use of the chemical formula to determine the number of atoms of each element in the compound.
  • Multiply the atomic weight of each element with its number of atoms present in the compound.
  • Add up all and assign unit as grams/mole.

Example : molar mass of SnO = atomic weight of Sn + atomic weight of O

molar mass of SnO =118.71 + 16 = 134.71 g / mol

For all the chemistry people out there. Explain why Benzene is more stable that 1,3,5-hexatriene? ...?
Triss [41]
Benzene is more stable because it contains a ring and therefore an aromatic compound. On the other hand, 1,3,5-hexatriene, as a straight-chain alkene, is aliphatic. Aromatic compounds in general are more stable than their aliphatic counterparts because pi electrons are part of a conjugated system, meaning they are "shared" amongst all double-bonded atoms.

A 25.0 g piece of aluminum (which has a molar heat capacity of 24.03 J/mol°C) is heated to 86.4°C and dropped into a calorimeter
Ira Lisetskai [31]

Answer:

m H2O = 56 g

Explanation:

  • Q = mCΔT

∴ The heat ceded (-) by the Aluminum part is equal to the heat received (+) by the water:

⇒ - (mCΔT)Al = (mCΔT)H2O

∴ m Al = 25.0 g

∴ Mw Al = 26.981 g/mol

⇒ n Al = (25.0g)×(mol/26.981gAl) = 0.927 mol Al

⇒ Q Al = - (0.927 mol)(24.03 J/mol°C)(26.8 - 86.4)°C

⇒ Q Al = 1327.64 J

∴ mH2O = Q Al / ( C×ΔT) = 1327.64 J / (4.18 J/g.°C)(26.8 - 21.1)°C

⇒ mH2O = 55.722 g ≅ 56 g
