हिन्दीThe mass of a single hydrogen atom is \( 0.00000000000000000000000166\text{ g} \). In proper scientific notation \( N \times 10^n \), this value is correctly written as:
Correct answer · Option 4
\( 1.66 \times 10^{-24}\text{ g} \)
Explanation
In scientific notation, the decimal is moved 24 places to the right to place one non-zero digit before the decimal point: \( 1.66 \times 10^{-24}\text{ g} \).
