Find the mass of an object that has a volume of 6.0 cm ³ and density of 3.3 g / ml.

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

volume = 6 cm³

density = 3.3 g/cm³

We have

mass = 3.3 × 6

We have the final answer as

Hope this helps you

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell

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.
