The atomic mass of gold is 197 g/mole, and the density of gold is 19.3 g/cm3. using this information along with the measured val
olganol [36]
The speed of sound is given by the formula
Speed of sound = square root (Young's Modulus/density)
Young's modulus for gold = 78 GPa which is 7.8 * 10^10 Pa
Speed of sound = (7.8 * 10^10 / 19.3 ) = sqrt (4.04 * 10^9 )
Speed of sound = 6.36 * 10^4 m/s <<<=== answer.

Explain the term conservation of mass
emmasim [6.3K]

The term conservation of mass means that mass in any system can neither be created nor destroyed but can be transformed from one state to another.

<h3>What is the law of mass of conservation?</h3>

The law of conservation states that the mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another.

This means that when an element is involved in a chemical reaction, it's mass remains the same at the end of that reaction.

1.505 times 10^23 Na atoms
dybincka [34]

5.75g

Explanation:

Given parameters:

Number of atoms = 1.505 x 10²³atoms

let us find the number of moles and mass of this atom.

Solution:

The mole is convenient unit for reporting measurements in chemistry. It allows us to make mathematical calculations:

     one mole of substance contains 6.02 x 10²³atoms

Number of moles of Na given = \frac{1.505 x 10^{23} }{6.02 x 10^{23} }  = 0.25moles

Mass of Na atom given = number of moles x molar mass

   Molar mass of Na= 23g/mole

Mass of Na = 0.25 x 23 = 5.75g

In which pair do both atoms have one electron only in an s orbital in their ground states?
Scrat [10]
I can help you only with what is electron in ground state. The electron which is not excited or over which no external force is acting that could possibly make it jump to the higher state,is said to be in its ground state.In excited state,the electron has more energy than it normally has. For convenience,suppose you are an electron,you are in Normal mood,but when your little brother snatches the Tv remote from your hand,you become angry.Your normal state is your ground state and your angry state is your excited state.
