NaOH will dissociate as Na+ and OH- in the solution.
Hey there!:
density = 3.51 g/cm³
Volume = 0.0270 cm³
Therefore:
D = m / V
3.51 = m / 0.0270
m = 3.51 * 0.0270
m = 0.09477 g

Answer: There are 576.46 number of grams present in 16.95 mol hydrogen peroxide
.
Explanation:
Number of moles is defined as the mass of substance divided by its molar mass.
The molar mass of
is 34.01 g/mol. Hence, mass of hydrogen peroxide present in 16.95 moles is calculated as follows.

Thus, we can conclude that there are 576.46 number of grams present in 16.95 mol hydrogen peroxide
.
