What is mass of 20 moles of Na2SO3

Answer 1

The molar mass of Na2SO3 (sodium sulfite) is calculated as follows:

2(Na) + S + 3(O) = 2(22.99) + 32.07 + 3(16.00) = 46.00 + 32.07 + 48.00 = 126.07 g/mol

Therefore, the mass of 20 moles of Na2SO3 is:

20 moles x 126.07 g/mol = 2521.4 grams

Therefore, the mass of 20 moles of Na2SO3 is 2521.4 grams.
