Answer:

Number of moles of solute = 0.175 mol

Explanation:

Given data:

Molarity of HF solution = 3.5 M

Volume of solution = 0.05 L

Number of moles of HF in solution = ?

Solution:

Formula:

Molarity = number of moles of solute / Volume of solution in L

Now we will put the values in above given formula.

3.5 M = number of moles of solute / 0.05 L

3.5 M × 0.05 L =  Number of moles of solute

         M = mol/L

Number of moles of solute = 0.175 mol

son4ous [18]

0001 M HCl is the same as saying that 1 *10-4 moles of H+ ions have been added to solution. The -log[. 0001] =4, so the pH of the solution =4.

A solution of ammonia and water contains 2.10×1025 water molecules and 7.10×1024 ammonia molecules. How many total hydrogen atom
Natali5045456 [20]

There are 6.33 × 10²⁵ hydrogen atoms in this solution in total.

<h3>Explanation</h3>
  • There are two hydrogen atoms in each water \text{H}_2\text{O} molecule.
  • There are three hydrogen atoms in each ammonia \text{NH}_3 molecule.

2.10 × 10²⁵ water molecules and 7.10 × 10²⁴ ammonia molecules will contain

2 \times 2.10 \times 10^{25} + 3 \times 7.10 \times 10^{24} = 6.33 \times 10^{25} hydrogen atoms in total.
