Peg 400 is a liquid with a specific gravity of 1.13. what volume should be measured for the preparation?

354 cm³

Explanation:

Step 1: calculate the density of PEG 400

= 1.13X1 = 1.13

Step 2:

Molecular weight of PEG 400 = 400g/mol

Step 3: calculate the volume of PEG 400 to be measured

                                       = 353.98 cm³

                                       ≅354 cm³

i think its c if i'm wrong

+15-35=-20

going in opposite directions
