Determine the molar mass of H2O2 (the solute) in a 1.5M aqueous solution of H2O2
Lera25 [3.4K]

Answer:

The molar mass of  H₂O₂ (the solute) in the aqueous solution of

H₂O₂ is 51 g

Explanation:

Given;

H₂O₂ compound

Concentration of aqueous solution of H₂O₂ = 1.5M

The molecular mass of H₂O₂ = (1 x 2) + (16 x 2) = 34 g/mol

Concentration(M) = \frac{Reacting \ mass \ (g)}{Molar \ mass \ (g/m)}

Reacting mass (g) = Concentration x Molar mass

Reacting mass (g) = 1.5 x 34

Reacting mass (g) = 51 g

Therefore, the molar mass of  H₂O₂ (the solute) in the aqueous solution of

H₂O₂ is 51 g

Rank the ions in each set in order of increasing size, and explain your ranking:
Paha777 [63]

Explanation:

Lithium, sodium and potassium are all group 1A elements and when we move down a group then there occurs an increase in atomic size of the elements. As lithium is the smallest and potassium being the largest so, when each of them will lose an electron and obtain a positive charge then size of lithium will further decrease.

Therefore, ions are ranked according to their increase in size as follows.

                      Li^{+} < Na^{+} < K^{+}  

When an atom tends to gain electrons then it acquires a negative charge. This means that size of the atom increases.  

So, more is the negative charge present on an atom more will be its atomic size. Therefore, correct order of increasing size for Se^{2-}, Rb^{+}, Br is as follows.

                      Br < Rb^{+} < Se^{2-}

Similarly, order of increasing size of O^{2-}, F^{-}, N^{3-} is as follows.

                    F^{-} < O^{2-} < N^{3-}
