In a chemical reaction, two molecules with a total mass of 76 amu react to form a single molecule. What is the mass of the molecule that is formed?(1 point) Responses 76 amu 76 amu 152 amu 152 amu 228 amu 228 amu 38 amu
Since two molecules react to form a single molecule, the total mass of the reactants should be equal to the mass of the product. Therefore, the mass of the molecule that is formed would also be 76 amu.
To determine the mass of the molecule that is formed in the reaction, you need to add up the masses of the two reacting molecules.
If the total mass of the two molecules is 76 amu, it means each molecule has a mass of 76 amu / 2 = 38 amu.
Therefore, the mass of the molecule that is formed is 38 amu.
To find the mass of the molecule that is formed in the chemical reaction, we need to determine the sum of the masses of the two reacting molecules. Given that the total mass of the two molecules is 76 amu, there are several possible combinations of masses for the two molecules.
Let's break down the options provided:
Option 1: 76 amu
This option suggests that the mass of the resulting molecule is equal to the total mass of the two reacting molecules. In a chemical reaction, the mass is conserved, which means that the total mass of the reactants should be equal to the total mass of the products. This option is a valid possibility.
Option 2: 152 amu
This option suggests that the mass of the resulting molecule is twice the total mass of the reacting molecules. However, this contradicts the law of conservation of mass, which states that mass is conserved in a chemical reaction. Therefore, this option is invalid.
Option 3: 228 amu
This option suggests that the mass of the resulting molecule is three times the total mass of the reacting molecules. Again, this contradicts the law of conservation of mass and is an invalid option.
Option 4: 38 amu
This option suggests that the mass of the resulting molecule is equal to half the total mass of the reacting molecules. Similar to options 2 and 3, this contradicts the law of conservation of mass and is an invalid option.
Based on these explanations, the correct answer is Option 1: 76 amu.
