To find this you have to find the molar mass of CO2 which you can get on the periodic table, 12 + 16 + 16 = 44 g/mol
4.49 x 10^0 / 44 g/mol = .1020 mol CO2
1 mol = 6.022 x 10^23 molecules (avogadros number)
so .1020 mol x 6.022 x 10^23 =
6.14 x 10 ^22 molecules CO2
Molecules consisted only of hydrogen and carbon elements are called hydrocarbons, or organic molecules since they are found in living things.
Depending on their structure and the chemical bonds between the elements, they can be divided into three groups :
1) saturated ( which have only single bonds between the hydrogen and carbon atoms eg. CH3-CH3 )
2)non-saturated ( which have two or three bonds between the carbon and hydrogen atoms eg. CH2=CH2)
3) aromatic (having the aromatic ring )
Answer:
If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots.
