Answer:

Concentration: The amount of a given substance within a set solution.

Explanation:

For example, the units for concentration include mol/ $dm^{3}$ which means that if a substance has 3 mol/ $dm^{3}$ , it means 3 moles of that substance is in a 1 dm cubed of that solution. You could give examples of the concentration of acids like Hydrochloric Acid (HCl) and alkalis like Hydroxide (OH).

B. 1) Tritium is the isotope of Hydrogen (H).

2) Mass of an Electron is 9.10938356 × 10-³¹ Kg.

3) Molecular mass of Carbon dioxide (CO2)

=> Molecular mass of carbon = 12g

Molecular mass of oxygen= 16g

molecular mass of CO2 = [12 + (16 X 2)]g

= (12 + 32)g

= 44 g
