Answer:- 14.94 grams of the product are formed.
Solution:- It is based on law of conservation of mass. The sum of masses of reactants taken must be equal to the sum of masses of products formed and remaining mass of the reactants.
9.11 g of A and 8.82 g of B are taken. After reaction, 1.38 g of A and 1.61 g of B are remaining. It asks to calculate the mass of the product formed. Let's use the law of conservation of mass and do calculations.
9.11 + 8.82 = mass of product + (1.38 + 1.61)
17.93 = mass of product + 2.99
mass of product = 17.93 - 2.99
mass of product = 14.94 g
So, for this problem, 14.94 grams of the product are formed.
