Hello!
A substance that could be found in air, water or soil that is harmful to humans or animals is a Pollutant.
The other substances cannot be found in air, water or soil. Fossil fuels can only be found in soil, smog can only be found in the air, and carbon dioxide can be found in the water or air.
Pollutants are substances that have harmful effects and damage the environment. Some examples of pollutants are Carbon Monoxide (air), Lead (soil) and Insecticides (water).
Have a nice day!
Answer:
Since oxygen (O) has an atomic mass of 16 g, oxygen gas (O2) has a molecular mass of 2 x 16 = 32 g. We need to convert the given amount of oxygen gas to moles and this can be done by dividing the given mass by the molecular weight of oxygen gas. Hence, moles of oxygen gas = 48 g / 32 g/mole = 1.5 moles.
