Determine the moles of LiOH using its molar mass: \( \text{moles of LiOH} = \frac{1.5 \text{ g}}{\text{molar mass of LiOH}} \).
Calculate the moles of HNO3 using its concentration and volume: \( \text{moles of HNO3} = 1.000 \text{ M} \times 0.0235 \text{ L} \).
Write the balanced chemical equation for the reaction: \( \text{LiOH} + \text{HNO}_3 \rightarrow \text{LiNO}_3 + \text{H}_2\text{O} \).
Determine the limiting reactant by comparing the moles of LiOH and HNO3.
Calculate the moles of Li+ remaining in solution, considering the stoichiometry of the reaction and the limiting reactant.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Stoichiometry

Stoichiometry is the calculation of reactants and products in chemical reactions. It involves using balanced chemical equations to determine the relationships between the amounts of substances consumed and produced. In this case, understanding the stoichiometric ratios between LiOH and HNO3 is essential to find out how much Li+ remains after the reaction.

Molarity

Molarity is a measure of concentration defined as the number of moles of solute per liter of solution. It is crucial for calculating the concentration of ions in a solution. In this question, the molarity of HNO3 is given, which will help determine how many moles of HNO3 are present and how they react with LiOH.

Neutralization Reaction

A neutralization reaction occurs when an acid reacts with a base to produce water and a salt. In this scenario, HNO3 (an acid) reacts with LiOH (a base) to form water and LiNO3. Understanding this concept is vital for determining the extent of the reaction and calculating the remaining concentration of Li+ in the solution.
