To calculate the moles of sodium in the can, we need to first convert the mass of sodium (12 mg) to grams:

12 mg = 0.012 g

Next, we need to use the molar mass of sodium (22.99 g/mol) to convert grams to moles:

0.012 g Na x (1 mol Na/22.99 g Na) = 0.000522 mol Na

Rounding to three significant figures gives us 0.00522 moles of sodium in the can. Therefore, the best choice is (A).
