The correct answer is: $67.63\text{ fl oz (US)}$
Explanation
2 liters converted to US fluid ounces uses the factor $1\text{ L}=33.8140226\text{ fl oz (US)}$, so multiply by 2.
Steps:
- Start with the conversion factor: $1\text{ L}=33.8140226\text{ fl oz (US)}$
- Multiply: $2\text{ L}\times33.8140226\text{ fl oz/L}=67.6280452\text{ fl oz}$
- Round to a sensible precision: $67.63\text{ fl oz (US)}$
Therefore, $2\text{ L}\approx67.63\text{ fl oz (US)}$.
Note: If you meant imperial (UK) fluid ounces instead, $1\text{ L}=35.1950797\text{ fl oz (imp)}$, so $2\text{ L}\approx70.39\text{ fl oz (imp)}$.
