Answer:
<h3>The answer is 5.0 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 100 g
volume = 20 mL
So we have

We have the final answer as
<h3>5.0 g/mL</h3>
Hope this helps you

Answer: extremely sensitive to environmental changes caused by habitat destruction, climate change, pollution
Explanation:
Across the world, amphibians have been disappearing at an unprecedented rate — faster than any other group of animals. Frogs, toads, and salamanders are extremely sensitive to environmental changes caused by habitat destruction, climate change, pollution, and invasive species.
Let our basis for the calculation be 1 mol of the substance.
(1 mol)(102 g/mol) = 102 g
Determine the amount of C, H, and O in mole.
C = (102 g)(0.588)(1 mol/12 g) = 4.998 mols C
H = (102 g)(0.098)(1 mol/1 g) = 9.996 mols H
O = (102 g)(0.314)(1 mol/16 g) = 2 mols O
The empirical formula of the substance is C5H10O2. The molar mass of the empirical formula is 102. This means that this is also its molecular formula.
