Question

What is the density of a substance that contains 850 milligrams for every mL? Express your answer in grams per cm³.

Answer 1

The density  of substance that contain  850 milligrams  for every  Ml  is  

0.85 g/Cm³

    calculation

 step 1:convert   850 Mg  to g

that is 1  mg=0.001 g

        850 mg =? g

= (850 mg   x  0.001  g)/ 1 mg=0.85 g

step 2:  convert  Ml  to  Cm³

           that is 1  Ml =  1 cm³

therefore density  = 0.85 g/Cm³
