To find the amount of sodium in 3 ounces of mixed nuts, you need to calculate the sodium content based on the per-ounce amount provided in the nutritional facts. If the nutritional facts state that there is 2.25 mg of sodium in a certain amount (like 5 cups or a specific weight), you need to find the sodium content for just 3 ounces.
The correct method involves determining how much sodium is in one ounce of mixed nuts and then multiplying by 3 ounces.
If 2.25 mg is for 5 cups of mixed nuts, you would first express this amount in terms of ounces (if needed) or directly work with the given amount and scale it down.
So, the best method would be:
Multiply 3 times 2.25 (if you mean that each ounce has 2.25 mg of sodium).
If 2.25 mg applies to a larger quantity than just 1 ounce, you would need to adjust accordingly.
Therefore, given the choices, the best option is:
multiply 3 times 2.25 (assuming 2.25 mg is the amount per ounce).
