Question

the mole can be used as a conversion from the atomic to the macroscopic scale. in order to do this molar mass is needed. calculate the molar mass of each chemical formula. type in the numerical response, such as 32.56. round the molar mass of each chemical to two decimal places. sr₃n₂

Explanation:

Step1: Find atomic masses

Atomic mass of Sr: $87.62\space g/mol$, atomic mass of N: $14.01\space g/mol$.

Step2: Calculate total mass for each element

For Sr: $3\times87.62 = 262.86\space g/mol$.
For N: $2\times14.01 = 28.02\space g/mol$.

Step3: Sum the masses

Molar mass of $Sr_3N_2$: $262.86 + 28.02 = 290.88\space g/mol$.

Answer:

290.88
