In determining the answer, we need to convert 880 torr to atm.
880 torr(1 atm/760 torr) = 1.157894737 atm (760 torr equals 1 atm)
Since water boils at 100 degrees Celsius at 1 atm, we multiply 1.157894737 atm with 100 degrees Celsius =
we would get 115.7894737 degrees Celsius.
Answer:
Explanation:
Mole = No. Of atom/Avogadro const
Avogadro constant= 6.02×10^23
Mass of Cu =22g
Molar mass of Cu =63.5g/mol
Mole = mass/molar mass
Mole = 22/63.5
Mole = 0.346
No. Of atom=mloe ×avogadro conts
No. Of atom = 0.346 × 6.02×10^23
No. Of atom = 2.09 × 10^23atoms
I think it’s d not 100% sure tho
