Answer: There are 4.8 grams in 100 mL of Drug A
Step-by-step explanation:
In order to determinate how many grams are in 100 mL of Drug A you can multiply and divide the expression of the concentration by 10 (To obtain 100 mL in the denominator)
Notice that the value remains unaltered.
(475 mg/10 mL )(10/10) = 4750 mg/ 100 mL
But the question is how many grams are in 100 mL, so you have to convert the value from mg to g.
The prefix m (mili) is equivalent to 0,001 so you can use 0.001 instead of the prefix
4750(0.001) g/ 100 mL
4.75 g/ 100 mL
The rounded result is 4.8 g/ 100 mL
