There are different formula you need to keep in mind when solving for [OH-]

Given that pH = 6.10

pH + pOH = 14

6.10 + pOH = 14

pOH = 7.9

[OH-] = 10^(-pOH)

[OH-] = 10^(-7.9)

[OH-] = 0.000000013

[OH-] = 1.3 x 10^-8

<h2>Answer: [OH-] = 1.3 x 10^-8</h2>

A ball was massed in a dish. The total mass was 15.6 grams. Treball was placed in a

iVinArrow [24]

Answer:

14.57g

Explanation:

Given parameters:

Mass of dish + ball = 15.6g

Initial volume of water in the cylinder = 26.7mL

Final volume of water in the cylinder = 38.9mL

Mass of dish = ?

Unknown

Mass of the ball = ?

Solution;

Since the mass of ball and dish is 15.6g,

Mass of the ball =Mass of ball + dish - mass of the dish

Insert the parameters and solve;

Mass of the ball = 15.6g - 1.03g = 14.57g

The total concentration of ions in a 0.75 M solution of HCl is

EastWind [94]

<h3>Answer:</h3>

The total concentration of ions in a 0.75 M solution of HCl is 1.5 M

That is; 0.75 M H⁺ and 0.75 M Cl⁻

<h3>Explanation:</h3>

Concentration or molarity is the number of moles of a compound or an ion contained in one liter of solution. It is measured in moles per liter (M).
The concentration of ions making a compound is determined by the ratio of moles of the compound and the constituents ions.

For instance, HCl dissociates to give H⁺ and Cl⁻

HCl(aq) → H⁺(aq) + Cl⁻(aq)

Therefore, since the mole ratio between HCl and the constituent ions H⁺ and Cl⁻ is 1:1, then 0.75 M of HCl dissociates to give 0.75 M H⁺ and 0.75 m Cl⁻
