To calculate how many grams of ibuprofen are in 0.525 mole, we need to follow these steps:

Find the molar mass of ibuprofen

Multiply the molar mass by the number of moles

Step 1: Find the molar mass of ibuprofen

Ibuprofen has the chemical formula C13H18O2

To calculate the molar mass, we need to sum the atomic masses of all atoms:

Carbon (C): 13 脳 12.01 g/mol = 156.13 g/mol

Hydrogen (H): 18 脳 1.008 g/mol = 18.144 g/mol

Oxygen (O): 2 脳 15.999 g/mol = 31.998 g/mol

Total molar mass = 156.13 + 18.144 + 31.998 = 206.272 g/mol

Step 2: Multiply the molar mass by the number of moles

Grams = molar mass 脳 number of moles

Grams = 206.272 g/mol 脳 0.525 mol

Grams = 108.2928 g

Therefore, 0.525 mole of ibuprofen is equal to approximately 108.29 grams.
