Assume complete dissociation. Strong monoprotic acids give [H⁺]=C and strong bases give [OH⁻]=C; use pH=14−pOH at 298 K.

Divide the total received energy by the energy of one 600 nm photon.

Translate every condition into an equation and retain exact values throughout the hyperbola calculation.

The last line satisfies the original conditions and supplies every requested part.

Using \(A=A\cap(A\cup X)\) and the given union equality,

Similarly,

Therefore \[\begin{aligned}A &= A\cap B\\&= B\end{aligned}\].

Name the inner functions, differentiate each factor, and then simplify.

Substitution into the original expression verifies the stated domain and final value.

Translate every condition into an equation and retain exact values throughout the hyperbola calculation.

The last line satisfies the original conditions and supplies every requested part.

Translate every condition into an equation and retain exact values throughout the straight-line calculation.

The last line satisfies the original conditions and supplies every requested part.

Translate the conditions into a sequence equation, then retain every admissible real solution.

The final value satisfies the original recurrence, sum, product or financial condition.

Proceed from the given expression and keep every transformation explicit.

The last line satisfies the required domain and establishes the result.

Convert each mass to moles, divide by solution volume, and account for the number of OH⁻ ions released. For HCl use the dilution relation.
