Identify the given values and conversion factor

Using the Ounce Conversion and Dimensional Analysis knowledge points
\[

$$\begin{aligned} &\text{Given mass in ounces } (m_{\text{oz}}) = 5.85\text{ oz}\\ &\text{Conversion factor } (C) = 28.3495\text{ g/oz} \end{aligned}$$

\]

Set up the conversion equation

Using the Dimensional Analysis knowledge point
\[
m_{\text{g}} = m_{\text{oz}} \times C
\]

Calculate the mass in grams

Using the Ounce Conversion knowledge point
\[

$$\begin{aligned} m_{\text{g}} &= 5.85\text{ oz} \times 28.3495\text{ g/oz}\\ m_{\text{g}} &\approx 165.844575\text{ g} \end{aligned}$$

\]

Match with the given options

Using the Ounce Conversion knowledge point
\[
m_{\text{g}} \approx 165.84\text{ g}
\]
