Answer

Explanation:

Step1: Identify the law of conservation of mass

According to the law of conservation of mass, in a chemical - reaction, the total mass of reactants equals the total mass of products.

Step2: Calculate the mass of the product

The mass of substance A is 10 g and the mass of substance B is 45 g. The mass of substance AB (product) is the sum of the masses of A and B. So, (m_{AB}=m_A + m_B). [m_{AB}=10 + 45=55\space g]

Answer:

C. 55 g
