text: # How to calculate the molar mass of aspirin?
  
  atyourservice | Student
  
  the chemical formula for aspirin is C9H8O4
  
  the molar mass of an element is it's atomic mass rounded to the nearest whole number, so:
  
  c- 12
  
  h- 1
  
  o - 16
  
  now multiply these number by how many of each there are in the formula:
  
  c - 12 x 9 = 108
  
  h - 1 x 8 = 8
  
  0 - 16 x 4 = 64
  
  add these numbers up
  
  108 + 8 + 64 = 180
  
  so 180g

  First, we need to recall the chemical formula of aspirin (acetylsalicylic acid): C9 H8 O4
  
  Now, we'll have to determine the mass of each component atom:
  
  The atomic mass of C = 12 g
  
  The atomic mass of H = 1 g
  
  The atomic mass of O = 16 g
  
  Now, we  need to multiply each atomic mass by the specific number of atoms:
  
  C9 = 9*12 = 108 g (1)
  
  H8 = 8*1 = 8 g (2)
  
  O4 = 4*16 = 64 g (3)
  
  Now, we'll add (1),(2),(3):
  
  C9 + H8 + O4 = 108 + 8 + 64 = 180 g
  
  The molar mass of aspirin is of 180 g.
