the sun cooks the clouds the clouds pee on the earth and all the water falls to earth, pushing all the wind down that's why we have earthquakes
Use the h-h equation!
pH = pKa + log[In-/HIn]
2.0 = 9.7 + log[In-/HIn]
-7.7 = log[In-/HIn]
10^-7.7 = [In-/HIn]
[In-/HIn] = 1.995 x 10^-8
Hope this helps!
The volume of Iron (in cm^3) = 4840/7.86 = 615.78 cm^3.
1 cm^3 = 1 mL and there are 1000 mL in 1 dL
So to convert from cm^3 to dL, we just have to divide by a 1000
615.78/1000 = 0.61578 dL
