The number of neutrons is variable, resulting in isotopes, which are different forms of the same atom that vary only in the number of neutrons they possess. Together, the number of protons and the number of neutrons determine an element's mass number.

Fossils are the preserved remains or traces of animals, plants, and other organisms from the past.

Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.

Usually only a portion of an organism is preserved as a fossil, such as body fossils (bones and exoskeletons ), trace fossils (feces and footprints), and chemofossils (biochemical signals).

Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.

How many milliliters are in 425 g of bromine if the density of bromine is 3.12 g/cm3
arlik [135]

Answer:

<h2>136.2 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

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

From the question

mass = 425

density = 3.12 g/cm³

We have

volume =  \frac{425}{3.12}  \\  = 136.2 \:  \:  {cm}^{3}

Since cm³ = mL

We have the final answer as

<h3>136.2 mL</h3>

Hope this helps you
