The answer is 'equal'. Hydroxide ions are OH- and Hydrogen ions are H+. Have you noticed they're opposite charges? Positive + negative = neutral. That's all there is to it :)
Answer: d = 7.9 g/cm^3
Identify the given information.
m = 79 g
v = 10 cm^3
Choose which formula you should use. In this case, you are finding the density.
d = m/v
Substitute and solve.
d = 79 g/10 cm^3
d = 7.9 g/cm^3
