Answer:
[H+] = 6.8×10^-11
so, pH = - log[H+]
= - log [6.8×10^-11]
= -(-10.167)
= 10.167
72.22 g
Explanation:
975 mL Mercury× 13.5 g/mL = 72.22 g
mass (m) = ? , volume = 18.0 ml , density = 1.42 g/ml .
I hope I helped you^_^
12,375 cm³
v=l×w×h
Since there are 3 books the equation would then be
v=3(l×w×h)
v=3(25×15×11)
v=3(4,125)
v=12,375 cm³
