SO3 + H2O -> H2SO4
given the atomic mass of hydrogen is 1amu, the atomic mass of oxygen is 16 amu, and one molecule of sulfuric acid has a mass of 98 amu, what is the atomic mass of sulfur trioxide?
A. 80 amu
B. 48 amu
C. 32 amu
D. 116 amu
To calculate the atomic mass of sulfur trioxide (SO3), we need to sum up the atomic masses of sulfur and 3 oxygen atoms.
Sulfur (S) atomic mass = 32 amu
Oxygen (O) atomic mass = 16 amu
SO3 atomic mass = (1*S) + (3*O)
SO3 atomic mass = 32 + (3*16)
SO3 atomic mass = 32 + 48
SO3 atomic mass = 80 amu
Therefore, the atomic mass of sulfur trioxide (SO3) is 80 amu.
A. 80 amu
