A 5.00 cm^3 sample of gold has a mass of 96.5 g. Calculate the density of gold.
Sholpan [36]

Answer:

\boxed {\boxed {\sf 19.3 \ g/cm^3}}

Explanation:

We are asked to calculate the density of gold. The density of a substance is its mass per unit volume. It is calculated using the following formula.

\rho= \frac{m}{v}

The mass of the sample is 96.5 grams. The volume of the sample is 5.00 cubic centimeters.

  • m= 96.5 g
  • v= 5.00 cm³

Substitute the values into the formula.

\rho= \frac{ 96.5 \ g}{5.00 \ cm^3}

Divide.

\rho= 19.3 \ g/cm^3

The density of gold is <u>19.3 grams per cubic centimeter.</u>

Orbitals give a probability map of where it is likely to find an electron in an atom.

Explanation:

Wave mechanical model of the atom suggests that an atom contains a nucleus which has positively charged protons and neutral neutrons.

The outer part of the atom is mostly empty.

The negatively charged electrons are located in outer orbitals.

The true statement is :

Orbitals give a probability map of where it is likely to find an electron in an atom.
