a material has a density of 8.9 g/cm^3. You have six cubic centimeters of the substance. What is the material's mass in grams?
Svet_ta [14]
If the formula for density=m/v, you can manipulate this formula to the the mass. After manipulation, you get the equation for mass to be: m=density * volume. With density and volume given, we can find the mass.

mass= (8.9) * 6 = 53.4grams

stira [4]

233.1g

Explanation:

Given:

Formula units of FeCl₃ = 8.65 x 10²³ formula units

Unknown:

Mass of the FeCl₃ = ?

Solution:

The formula unit is the same as the amount of subatomic particles in an atom.

  1 mole of a substance = 6.02 x 10²³ formula units

 For  8.65 x 10²³ formula units; the number of moles;

  Number of moles = \frac{8.65 x 10 ^{23} }{6.02 x 10^{23} } = 1.44moles

Now to find the mass of  FeCl₃;

   Mass of  FeCl₃ = 1.44 x 162.2 = 233.1g
