the atomic mass of nitrogen is 14.01, hydrogen is 1.01, sulfur is 32.07, and oxygen is 16.00. what is the molar mass of ammonium sulphate (nh₄)₂so₄?\na. 63.09 g\nb. 84.17 g\nc. 114.12 g\nd. 118.16 g\ne. 132.17 g

Answer

Explanation:

Step1: Calculate nitrogen mass

There are 2 nitrogen atoms in $(NH_4)_2SO_4$. So mass of nitrogen is $2\times14.01 = 28.02$ g/mol.

Step2: Calculate hydrogen mass

There are 8 hydrogen atoms. Mass of hydrogen is $8\times1.01=8.08$ g/mol.

Step3: Calculate sulfur mass

There is 1 sulfur atom. Mass of sulfur is $1\times32.07 = 32.07$ g/mol.

Step4: Calculate oxygen mass

There are 4 oxygen atoms. Mass of oxygen is $4\times16.00=64.00$ g/mol.

Step5: Calculate molar mass of ammonium sulfate

Add up the masses of all elements: $28.02 + 8.08+32.07 + 64.00=132.17$ g/mol.

Answer:

E. 132.17 g
