The answer is TRUE.
Energy is an extensive property, which means that it is in proportion to the amount of matter: more mass, more energy.
You can measure, for example, the internal energy per mol or per gram of several compounds or elements. then if you want to know the total internal energy of the system you have to multiply by the number of moles or grams, depending on the unit of the internal energy that you use.

Answer:
a. 0.14 M
Explanation:
Molarity is the molar concentration of a solution and can be calculated using the formula below:
Molarity (mol/L) = number of moles (lol) ÷ volume (L)
To convert the mass of CO2 to moles, we use the formula: mole = mass/molar mass.
Molar mass of CO2 = 12 + 16(2)
= 12 + 32
= 44g/mol
mole = 2.2/44
mole = 0.05mol
Volume of can = 335mL = 335/1000 = 0.335L
Molarity = n/V
Molarity = 0.05/0.335
Molarity = 0.149
Molarity = 0.14 mol/L or M
