M(NaOH)=15 g
v=600 ml=0.6 l
n(NaOH)=m(NaOH)/M(NaOH)
C=n(NaOH)/v=m(NaOH)/[M(NaOH)v]
C=15g/[40g/mol*0.6 l]=0.625 mol/l
0.625M
[H⁺]=7.5*10⁻²
pOH=14-pH=14+lg[H⁺]
pOH=14+lg(7.5*10⁻²)=14-1.125=12.875
Gases use Cubic Feet (cu.ft).
28,317 cc (cm³ or mL).
For liquids we have the US Gallon (gal).
1.0 US gal. = 3,785 cc (cm³ or mL).
I think the answer would be F because the A has trees,B has trees,C has trees,D is very sandy,and E has no snow
