Answer:
The amount of air is 11.1 mmol
Explanation:
Density shows the relation between mass and volume, so you can know the mass which has been sealed in the Erlenmayer.
Density = mass/ volume
Density . volume = mass
0.001185 g/ml . 272.2 ml = 0.322 g
We have the mass now, so the molar weight determinates the mols
Mass/molar weight = mol
0.322g/ 28.96 g/m = 0.0111 mol
To get a better number we can inform on milimols
Mols . 1000 = milimols
There are 79 protons in the nucleus of one gold atom.
I would have to say bioconversion
Answer:
Land fill
Explanation:
A landfill is a carefully managed waste disposal site. It is the oldest method of waste disposal. In a dumpsite, biodegradable materials decay overtime.
However, non-biodegradable materials such as plastics and other polymers tend to last many years in landfills. This category of wastes pose a great threat to the environment.
