The Earth is divided into three chemical layers: the Core [Inner Core (D) and Outer Core (C)], the Mantle (B) and the Crust (A). The Core is predominantly composed of iron and nickel. Even after 4.5 billion years of cooling, the Earth's core remains very hot.
Answer:
NaCl is the correct answer
Answer:
I think it's 7089 because that's my answer to your questions
First convert mL to L:
(500. mL)/(1000L) = .500L
Then convert molarity to moles:
(3.00M)(.500L) = 1.5mol NaCl
Then convert moles of NaCl to grams of NaCl by multiplying it by its molar mass:
(1.5mol NaCl)(58.44g/mol NaCl) = 87.66g NaCl are needed
