To determine the formula mass of beryllium chloride, BeCl₂, we start up with the basis of one mole first.
Basis: 1 mole BeCl₂
To determine the molar mass of BeCl₂, we add up the mass of one mole of beryllium and two moles of chlorine.
1 mol Be = 9 g/mol
1 mol of Cl = 35.45 g/mol
Solving,
molar mass of BeCl₂ = (1 mol Be)(9 g/mol) + (2 mols Cl)(35.45 g/mol)
molar mass of BeCl₂ = 79.9 g
Then, we take into consideration that 1 mol is equal to 6.022 x 10²³ formula units.
formula mass BeCl₂ = (79.9 g/mol)(1 mol/6.022 x 10²³ formula units)
formula mass of BeCl₂ = 1.33 x 10⁻²² g/formula unit
<em>Answer: 1.33 x 10⁻²² g/formula unit</em>
Answer:
Nitrogen is an inert gas — meaning it doesn't chemically react with other gases — and it isn't toxic. But breathing pure nitrogen is deadly. That's because the gas displaces oxygen in the lungs. Unconsciousness can occur within one or two breaths, according to the U.S. Chemical Safety and Hazard Investigation Board.
