Question

Consider a hypothetical reaction in which A and B are reactants and C and D are products. If 19 g of A completely reacts with 26 g of B to produce 17 g of C, how many grams of D will be produced?

Answer 1

Given reaction:

A + B ------ C + D

mass of A = 19 grams

Mass of B = 26 grams

Mass of C = 17 grams

To determine: The mass of D

Explanation:

As per the law of conservation of mass, in any chemical reaction the sum of masses of the reactants and products must remain unchanged.

Sum of masses of reactants = Sum of masses of products

19 g + 26 g = 17 g + D

Mass of D = (19+26) - 17 = 28 g

Answer 2

The study of chemicals and bonds is called chemistry. There are different types of elements and these are metals and nonmetals.

The correct answer is 28g

What is molar mass?

• The molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles

The reaction is as follows:-

A + B ------ C + D

The data is given as follow:-

• Mass of A = 19 grams
• Mass of B = 26 grams
• Mass of C = 17 grams

As per the law of conservation of mass, in any chemical reaction, the sum of masses of the reactants and products must remain unchanged.

Sum of masses of reactants = Sum of masses of products

$19 g + 26 g = 17 g + D$

Hence, The Mass of D = (19+26) - 17 = 28 g.
