A balance and a graduated cylinder are used to determine the density of a mineral sample. The sample has a mass of 14.7 g and a volume of 2.2 cm3. What is the density of the mineral sample?

The answer is

Explanation:

The density of a substance can be found by using the formula

From the question

mass of mineral = 14.7 g

volume = 2.2 cm³

It's density is

We have the final answer as

Hope this helps you

6.68g/cm³

Explanation:

The formula is [ d = m/v ] where m = mass and v = volume.

We are given both "m" and "v" so we can solve using those variables.

d = 14.7/2.2

d ≈ 6.68

Best of Luck!

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

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

will have a gram-molecular weight of 352g.
