Density = mass/Volume or D = m/V Given: V = 22.3 gal D = 0.8206 g/mL1) Rearrange the equation to solve for m2) Find conversion factor(s) and convert V from gal to mL (by dimensional analysis) so the units cancel3) Solve for m in g4) Find conversion factor(s) and convert m from g → lbs1) D = m/V rearranges to m = D ∗ V2) 1 gal = 3.785 L and 1 L = 1000 mL; 22.3 gal ∗ 3.785 L/1 gal ∗ 1000 mL/1 L = 84 406 mL 3) m = 0.8206 g/mL ∗ 84 406 mL = 69 260 g 4) 1 lb = 453.6 g; 69 260 g ∗ 1 lb/453.6 g = 153 lbsLearn More about Density:https://brainly.com/question/24386693
