Balance and a graduated cylinder are used to determine the density of a mineral sample to sample has a mass of 14.7 g and a volume of 2.2 cm3 what is the density of the mineral sample

Hey there!:

Mass = 14.7 g

Volume = 2.2 cm³

Density = ?

Therefore:

D = m / V

D = 14.7 / 2.2

D = 6.67 g/cm³

Answer J

Hope that helps!

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
