Math help

I need help with a pretty simple math question that I can't seem to wrap my mind around. Math, as you may know by some of my posts, is not my strong point.

If I have 2% of salt in a recipe (hot sauce) and I need to find the mg per 5mL serving (assuming specific gravity is 1- I'll check it later)....

2 grams in 100 grams times 1000 grams is 2000. Divide by 5 grams (converting from 5 mL) is 200mg. Is that right? That seems high, as my hot sauce doesn't seem as salty as some that list up to 150 mg sodium.

It just occured to me.....salt is sodium chloride. NOT pure sodium. So, 1.5g salt is 590 sodium (from the nutritional label on the salt). 1500mg divided by 590 is 25.42 (% sodium in sodium chloride). So does that make my hot sauce 79mg sodium (rounding to whole number)? This makes more since.

So, is my math any good?
