Answer:

Ounces of sodium required = 1.6 oz

Step-by-step explanation:

Given:

Mass of sodium = 45 g

To determine:

Mass of the given amount of Na in units of 'ounces' (oz)

Calculation:

Unit conversion:

1 g = 0.03527 oz

The given mass in oz is:


= (45\ g* 0.03528\ oz)/(1\ g) =1.587 oz

Rounding to 2 significant figures gives mass of Na = 1.6 oz
