Normality and n-factor Calculation

JEE Main asked Normality and n-factor Calculation 5 times in 5 of the 108 shifts Lumi analysed, in 2020, 2021, 2022 and 2023. It belongs to Mole Concept, in Some Basic Concepts of Chemistry (Chemistry). The longest wait between two years asking it was 1 year. In 2022 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2020, 2021, 2022 and 2023. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.
