apologiabiology
1tablet=0.025ml
1 times 500=500
multiply both sides by 500
500 tablets=500 times 0.025ml
500 tables=12.5ml

answer is C

all you have to do here is multiply what one tablet has times 500 tablets sooo
here is the math
0.025 x 500 = 12.5 
so that means there is 12.5 milligrams of magnesium in 500 tablets ;)
