(C) In scientific notation, every number is expressed as $a 	imes 10^{b}$, where $a$ is a number between $1$ and $10$, and $b$ is any positive or negative integer exponent.Significant figures are determined only by the digits in the coefficient $a$.The power of $10$ (i.e.,$10^{22}$) is irrelevant to the determination of significant figures.In the given value $3.78 	imes 10^{22}$, the coefficient is $3.78$.Since all non-zero digits are significant, the number of significant figures in $3.78$ is $3$.
