A metal sample weighs 57.3g and has volume of 6.3mL what is the density of the sample
PilotLPTM [1.2K]

Answer:

<h2>9.10 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question we have

density =  \frac{57.3}{6.3}  \\  = 9.095238...

We have the final answer as

<h2>9.10 g/mL</h2>

Hope this helps you

What is the binding energy of an electron in a metal whose threshold frequency for photoelectrons is?
jeka57 [31]

The binding energy of electrons in a metal is 193 kJ mol ^-1 .

<h3>What is binding energy?</h3>

The minimal amount of energy needed in physics and chemistry to separate a particle from a system of particles or to break a system of particles down into its component pieces is known as the binding energy.  While the word separation energy is used in nuclear physics, the former meaning is more common in condensed matter physics, atomic physics, and chemistry.

The energy level of a bound system is often lower than that of its unbound components. Relativity theory states that a drop in a system's total energy of E leads to a corresponding decrease in its total mass of m, where

Δmc² = E.

106. Describe the process scientists use when they study fossils. Include where fossils could be found and what steps scientists
Studentka2010 [4]
The process scientists use is simple: dig, brush, repeat. Fossils can be found in areas that once had living organisms, like lakesides and lake bottoms. To protect them they use a chemical coating.
