На жаль, для виконання розрахунків потрібно мати більше вхідних даних.

1) Не вказано обсяг розчину калій гідроксиду, з якого витрачається луг. Тому ми не можемо визначити кількість калій гідроксиду, який буде витрачений. Також не вказано, який обсяг розчину масовою часткою лугу 20% потрібно для добування 227,2 г мила.

2) Не вказано, який об'єм триолеїну було взято і яку концентрацію водню мали використовувані. Тому ми не можемо визначити кількість речовини жиру, що прореагував.

Будь ласка, надайте більше інформації
