Not sure how to solve this density question...?

Question

Lead has a density of 11.4 grams per mL. If I make a statue out of 3.45 L of lead, what is the

statue's mass?

Answer 1

start by converting it to grams per liter (multiply by 1000)

11400 g/L

multiply by the amount of L used (3.45)

393300g

convert to kg (divide by 100)

393.3 kg

Answer 2

Gee, Jay, unless I'm missing something,(and I do more times than I like to admit), this seems really easy. They tell you every ml. of Lead weighs 11.4 grams. Well, you know there are 1000 ml. in one liter so there's 3450ml. in 3.45 liters,( it's just 1000 x 3.45). So if there's 3450ml. of lead and each ml. weighs 11.4 grams. All you need to do is multiply 3450 x 11.4 = 39,330 g. Of course, you wouldn't ordinarily express your answer in grams when there are so many, you'd use kg., so it's 39.33 kg.
