The specific gravity of iron is 7.87, and the density of water at 4.00 ∘ c is 1.00 g/c m 3 . you can use this information to find the density of iron. find the volume occupied by 6.00 g of iron

The volume of 6.00g iron is 0.762 cm^3.

Step 1. Calculate the density of Fe

The specific gravity (SG) of a substance is the ratio of its density to the density of water at 4 °C.

SG = density of substance/density of water.

∴ 7.87 = density of iron/1.00 g·cm^(-3)

Density of Fe = 7.87 × 1.00 g·cm^(-3) = 7.87 g·cm^(-3)

Step 2. Calculate the mass of Fe

Volume of Fe = 6.00 g Fe × (1 cm^3 Fe/7.87 g Fe) = 0.762 cm^3

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.
