What is the mass loss during the reaction assume 1 mol of

Question

Now, consider 1 g of nuclear fuel. A common fission reaction is

²³⁵U + ¹n →⁹¹Kr + ¹⁴²Ba + 3 ¹n.

The masses of these species (in g/mol) are

²³⁵U 235.0439

⁹¹Kr 90.9235

¹⁴²Ba 141.9164

¹n 1.0087

What is the mass loss during the reaction? Assume 1 mol of ²³⁵U decays. Enter a positive number._________g
