Find the average atomic mass for li if 7.5% of li atoms are 6li with a mass of 6.0151223 amu and 92.5% are 7li with a mass of 7.0160041 amu.

6.94 amu

Explanation:

Step 1: Given data

Step 2: Calculate the average atomic mass (aam) of Li

We will use the following expression.

aam = m⁶Li × ab⁶Li + m⁷Li × ab⁷Li

aam = 6.0151223 amu × 0.075 + 7.0160041 amu × 0.925

aam = 6.94 amu

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
