Calculate the number of moles in each of the following:
I. 11g of `CO_(2)`
II. `N_(A)//4` molecules of `CO_(2)`
III. 1.12 L of `CO_(2)` at STP

Options

A. a-0.25, 0.25, 0.25
B. b-0.25, 0.05, 0.05
C. c-0.05, 0.25, 0.25
D. d-0.25, 0.25, 0.05

Answer

D

Explanation

I. `(11)/(4$) = 0.25` moles of `CO_(2)`
II. `(3.01 xx 10^(22))/(N_(A)) = (1)/(20)` moles of `CO_(2) = 0.05` moles of `CO_(2)`
III. `(1.12)/(22.4) = 0.05` moles of `CO_(2)`
