what is the mass of (nh4)2so4?\no 114. g\no 118. g\no 128. g\no 132. g

Explanation:

Step1: Identify atomic masses

The atomic masses of N = 14 g/mol, H = 1 g/mol, S = 32 g/mol, O = 16 g/mol.

Step2: Calculate mass of each element in the compound

For N: There are 2 N atoms in ((NH_{4}){2}SO{4}), so mass of N is (2\times14 = 28) g/mol. For H: There are (2\times4 = 8) H atoms, so mass of H is (8\times1=8) g/mol. For S: There is 1 S atom, so mass of S is 32 g/mol. For O: There are 4 O atoms, so mass of O is (4\times16 = 64) g/mol.

Step3: Calculate molar - mass of ((NH_{4}){2}SO{4})

Add up the masses of all elements: (28 + 8+32 + 64=132) g/mol.

Answer:

D. 132 g
