A sample of iron has a volume of 12 mL. If the mass of this object is 94 g, what is the density of iron? Will it sink or float in water? *

density = 7.83g/mL

It will sink in water.

Explanation:

D = mass/volume

94/12 = 7.83 g/mL

density of water is 1g/mL

Object is more dense than water, meaning it will sink.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
