Determine the density of gold if a 475.09g sample occupy a space of 24.6cm^3
Ira Lisetskai [31]

Answer:

The answer is

<h2>19.31 g/cm³</h2>

Explanation:

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

density =  \frac{mass}{volume}

From the question

mass of gold = 475.09g

volume = 24.6 cm³

The density of the gold is

density =  \frac{475.09}{24 .6}  \\  = 19.3126016...

We have the final answer as

<h3>19.31 g/cm³</h3>

Hope this helps you

How does removing trees affect nitrogen cycling in a forest ecosystem?
nikdorinn [45]

Explanation:

The roots of trees in a forest are colonized by symbiotic fungi called mycorrhizae. These fungi are significant nitrogen fixers because they harbor nitrogen-fixing bacteria. They convert atmospheric nitrogen into nitrates and nitrites that can be absorbed by plants. The plants use these forms of nitrogen to build biomolecules such as DNA and amino acids.This nitrogen is transferred up the food chain. Eventually the nitrogen is again recycled by denitrifiers when the organisms die.

Removing trees will disrupt the symbiotic relationship with mycorrhizae, stime the nitrogen cycle in the forest.
