Answer:
7000 mg
Step-by-step explanation:
to convert grams into milligrams you have to multiply by 1000, 7 times 1000 is 7000
I think it's 7000 mg because 1 gram equals to 1000 milligrams and so well if 1 gram equals to 1000 so 7 gram would be more and we have to multiply 1000 by 7 which give us 7000
