Question

Refer to the example about diatomic gases A and B in the to do problems 20-22. What is the mass of one mole of product? (Remember the law of conservation of mass)

a) g
b) 2g
c) 4g
d) 8g

Answer 1

The mass of one mole of a substance is equal to its molar mass. In this question, the mass of one mole of product can be determined by converting the mole quantities of the diatomic gases A and B to grams using their molar masses and comparing the results.

Step-by-step explanation:

The mass of one mole of a substance is equal to its molar mass. By using the molar mass, we can determine the mass of one mole of product. In the given question, the mass of one mole of product can be determined by converting the mole quantities of diatomic gases A and B to grams using their molar masses. Then, we can compare the masses to determine the mass of one mole of product.

For example, if 1 mole of substance A has a mass of 28.02 g and 1 mole of substance B has a mass of 6.06 g, we can conclude that the mass of one mole of product is 34.08 g (28.02 g + 6.06 g).

Therefore, the correct answer is 34.08g (option c).
