Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
The given compound contains one carbon atom, four hydrogen atoms and one oxygen atom.
It is an alcohol with functional group -OH and with molecular formula of named as methanol.
The molecular formula of the molecule is
Answer:
the property of air shown in the figure describe A.mass
Answer:
Temperature and Heat Temperature is the measure of the thermal energy of a substance. The hotter an object, the greater the motion of its particles, and the greater the thermal energy. Heat is the transfer or exchange of thermal energy caused by a temperature difference.
Explanation:
Rate of Effusion of Unknown gas = rX = 0.5
Rate of Effusion of Hydrogen = rH = 1
M.mass of Hydrogen = mH = 2 g/mol
M.mass of Unknown gas = mX = ?
Formula used:
rH / rX = √mX / mH
taking square on both sides,
r²H / r²X = mX / mH
Solving for mX,
mX = (r²H ÷ r²X) × mH
Putting values,
mX = [1² ÷ (0.5)²] × 2 g/mol
mX = (1 ÷ 0.25) × 2 g/mol
mX = 4 × 2 g/mol
mX = 8 g/mol
Result:
Molecular Mass of Unknown gas is 8 g/mol.
