The number of atoms present in 2.5moles of a triatomic gas is equivalent to [1mole = (6.02times 10^{23})]
-
A.
(2.5times 10^{23}) -
B.
(1.5times 10^{23}) -
C.
(1.5times 10^{24}) -
D.
(2.5times 10^{24})
Correct Answer: Option C
Explanation
1 mole = (6.02 times 10^{23})
2.5 moles = (6.02 times 10^{23} times 2.5)
= (15.05 times 10^{23} = 1.505 times 10^{24})
(approxeq 1.5 times 10^{24})
