How many atoms are contained in 0.2moles of nitrogen? ([N_{A} = 6.02 times 10^{23}])

How many atoms are contained in 0.2moles of nitrogen? ([N_{A} = 6.02 times 10^{23}])

  • A.
    (1.20 times 10^{23})
  • B.
    (2.41 times 10^{23})
  • C.
    (3.62 times 10^{23})
  • D.
    (4.82 times 10^{23})
Correct Answer: Option A
Explanation

(1 mole = 6.02 times 10^{23} atoms)

(0.2 moles = 6.02 times 10^{23} times 0.2) atoms

= (1.204 times 10^{23})

(approxeq 1.2 times 10^{23})
