question 13 the molar mass of c₂h₄(nh₂)₂ is blank 1 g/mol. blank 1 add your answer

Explanation:

Step1: Identify atomic masses

Carbon (C) has an atomic mass of approximately 12 g/mol, hydrogen (H) has 1 g/mol, nitrogen (N) has 14 g/mol.

Step2: Calculate molar mass of (C_2H_4(NH_2)_2)

There are 2 C atoms: (2\times12 = 24) g/mol. There are (4 + 2\times2=8) H atoms: (8\times1 = 8) g/mol. There are 2 N atoms: (2\times14 = 28) g/mol.

Step3: Sum up atomic - mass contributions

(24 + 8+28=60) g/mol.

Answer:

60
