The number of moles used by each compound

1. mol of C₂H₆N₄O₄ : = 0.0171

2. mol of C₇H₅N₃O₆ : = 0.0113

3. mol of CH₃NO₂ : = 0.042

Further explanation

Mole itself is the number of particles contained in a substance  

1 mole = 6.02.10²³ particles  

Mole can be determined if the amount of substance mass and its molar mass is known  

[tex]\tt \boxed{\bold{n=\dfrac{m}{M}}}}[/tex]

  • 1. mol of C₂H₆N₄O₄

= mass : molar mass

= 2.56 : 150.09 g/mol

= 0.0171

  • 2. mol of C₇H₅N₃O₆

= mass : molar mass

= 2.56 : 227,13 g/mol

= 0.0113

  • 3. mol of CH₃NO₂

= mass : molar mass

= 2.56 : 61,04 g/mol

= 0.042
