Answer:
24.97 g of C
Explanation:
Molar Mass of Ibuprofen is 206.29 g/mol
Molecular Formula of Ibuprofen is C₁₃H₁₈O₂
Also, 13 C atoms has mass of 12.01 × 13 = 156.13 g
Percentage of C in Ibuprofen,
% age of C = 156.13 / 206.29 × 100 = 75.68%
Now calculate 75.68 % of 33 g as,
75.68 % = x / 33 g × 100
x = 75.68 × 33 / 100
x = 24.97 g of C
