Answer 1

Converting 2.41 pints to ml: 2.41 pints x 473.176 ml/pint = 1140 mls 

Using density, find grams:  1140 mls x 7.28 g/ml = 8299 g

Convert to kg:  8299 g x 1 kg/100 g = 8.299 kg = 8.30 kg

OR

Converting mls to liters:  1140 mls x 1 L/1000 mls = 1.140 L

Converting density to kg/L:  7.28 g/ml x 1 kg/1000 g x 1000 ml/L = 7.28 kg/L

Finally, convert 1.140 L to kg using the density:  1.140 L x 7.28 kg/L = 8.30 kg
