Given that the density of iron is 11.35 grams per centimeter cubed, what would be the volume of a 1.1 gram piece of iron?

Explanation:

Density of a substance can be found by using the formula

From the question

Density = 11.35 g/cm³

mass of iron = 1.1 g

To find the volume substitute the values into the above formula and solve for the volume

That's

Making volume the subject we have

So we have

= 0.096916

We have the final answer as

Hope this helps you

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

where are the choice options?
