Answer:
Mass = 1257.71 ×10²³ g
Explanation:
Given data:
Number of molecules of C₃H₆ = 180 molecules
Atomic mass of C = 12.01 amu/atom
Atomic mass of H = 1.008 amu/atom
Mass of C₃H₆ = ?
Solution:
1 mole contain 6.022×10²³ molecules
180 molecules × 1 mol / 6.022×10²³ molecules
29.89×10²³ mol
Mass of C₃H₆:
Mass = number of moles × molar mass
Molar mass = 12.01×3 + 1.008×6 = 42.078 g/mol
Mass = 29.89×10²³ mol × 42.078 g/mol
Mass = 1257.71 ×10²³ g
