Question

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
