A scientist makes a boric acid (H3BO3) solution by dissolving 22.5 g of H3BO3 in water to make 750.0 mL of solution. Calculate t
GaryK [48]

Answer:

The correct answer is 0.36 mol

Explanation:

First we have to calculate the molecular weight (Mw) of H₃BO₃ from the molar masses of the elements:

Mw(H₃BO₃)= 3 x Molar mass H + Molar mass B + (3 x Molar mass O)

                  = 3 x 1 g/mol + 10.8 g/mol + (3 x 16 g/mol)

                  = 61.8 g/mol

The molecular weight indicates that there are 61.6 grams per mol of substance. The scientist has 22.5 g, thus we can calculate the number of moles of H₃BO₃ by dividing the mass into the molecular weight as follows:

Number of moles of H₃BO₃ = mass/Mw= (22.5 g)/(61.8 g/mol) = 0.36 mol

There are 0.36 mol of H₃BO₃ in 750.0 mL of solution.

In the following equation, ______ is being oxidized and ______ is being reduced.
Mashcka [7]

oxidation \: number \: of \: oxygen =  \\ before \: rxn =  - 2 \\ after \: rxn =  - 2

oxidation \: number \: of \: hydrogen = \\ before \: rxn =  + 1 \\ after \: rxn =  \\ 2x - 2 = 0 \\ x =  + 1

oxidation \: number \: of \: carbon =  \\ before \: rxn =  \\ x  - 6 =  - 2 \\ x = 4 \\ after \: rxn =  \\ x - 4 = 0 \\ x = 4

<h2>Option A</h2>

oxidation \: numbers \: remain \: constant \\ so \: none \:a re \: undergoing \: oxidation \: \\ nor \: reduction \:
