Its melting point is -75 °C.
It is highly flammable.
It is highly toxic.
It is irritant.
It is corrosive in nature.
Answer: 2.30x10²⁴ molecules CO2
Explanation: Solution:
Convert mass of CO2 to moles
Convert moles of CO2 to molecules using Avogadro's number.
168.2 g CO2 x 1 mole CO2 / 44 g CO2 x 6.022 x10²³ molecules CO2 / 1 mole CO2
= 2.30 x10²⁴ molecules CO2
The sample of carbon dioxide weighing 168.2 grams contains approximately 2.30 x 10^24 molecules. This is calculated by first converting the sample mass to moles, and then multiplying by Avogadro's Number.
To calculate the number of molecules in a sample, you need to know the formula for the substance and the molar mass of the substance. For carbon dioxide (CO2), the molar mass is 44.01 grams/mole.
The sample mass is 168.2 grams, so to calculate the number of moles, we divide the mass of the sample by the molar mass:
Number of moles = Sample Mass / Molar Mass =168.2 grams / 44.01 grams/mole = 3.82 moles (rounded to two decimal places).
The number of molecules is then calculated by multiplying the number of moles by Avogadro's Number (6.022 x 10^23 molecules/mole):
Number of molecules = Number of Moles x Avogadro's Number = 3.82 moles x 6.022 x 10^23 molecules/mole = 2.30 x 10^24 molecules (rounded to two decimal places).

The two products derived from ethylene are polyethylene resin and ethylene glycol.
Ethylene is the simplest form of organic compounds and is also known as an alkene. It contains carbon-carbon double bonds.
Ethylene is colourless and is also flammable. It also has a sweet taste and odour.
Ethylene belongs to a group of plant growth regulators which are widely used for ripening fruits and for the production of more flowers and fruits.
Ethylene is an important industrial organic chemical.
Therefore, The two products derived from ethylene are polyethylene resin and ethylene glycol.
