113.5 mL of `NO_(2)` at STP was liquefied, the density of the liquid being 1.15g `mL^(-1)`. Calculate the volume of `NO_(2)` and the number of molecules in the liquid `NO_(2)`. (At wt. N =14)
A. 0.10 mL and `3.01 xx 10^(22)`
B. 0.20 mL and `3.01 xx 10^(21)`
C. 0.20 mL and `3.01 xx 10^(23)`
D. 0.40 mL and `6.02 xx 10^(21)`
