Question

calculate the molecular masses of the following substance B2 and Sulphur dioxide as SO2

Answer 1

Sulphur dioxide - 64.066 g/mol

Answer 2

To find the molecular mass of SO2, you’re going to need to find the atomic mass of SO2. The atomic mass of sulfur is 32AMU, and the atomic mass of oxygen is 16AMU, then times two due to the subscript, so 32. Add those up, and 32+32=64AMU, which is your atomic mass for the whole. So your answer comes out to 64AMU, which is the molecular mass of SO2. Hope this helped you some.
