The density of the spoon : 1.2 g/cm³
<h3>Further explanation</h3>
Given
mass of the spoon = 30 g
volume = 25 ml
Required
Density
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
Density formula:
ρ = density
m = mass
v = volume
Input the value :
ρ = 30 g : 25 ml
ρ = 1.2 g/ml

Hello.
The answer is: Test
To test a hypothesis you test it with a test to prove if your correct or wrong.
Have a nice day
Answer:
The sample obtained from the environment has a higher mass
Explanation:
A simple way to put the answer is that the element carbon -as found in nature- has a molar mass of 12.0107 g/mol, because there are a few isotopes of 14C and 13C; and <em>the molar mass is an expression of the isotopes' natural abundance</em>.
So 1 mole of carbon obtained from the environment would weigh 12.0107 g, while a sample of isotopically pure carbon would weigh 12.0000 g.
