Question

how many significant figures does each measurement have?

\\(1.7 \times 10^{-6}\text{ cm}\\) = 2 significant figures

\\(3 \times 10^8\text{ g}\\) = significant figures

Explanation:

Identify the given value

$$ 3 \times 10^8\text{ g} $$

Determine the significant figures in the coefficient

$$ \text{Coefficient} = 3 \implies 1\text{ significant figure} $$

State the final count

$$ \text{Significant figures} = 1 $$

Answer:

\(3 \times 10^8\text{ g} =\) <blank>1</blank> significant figures
