1. Avogadro's number Na is defined as the number of particles (e.g. 1 mole) such that the mass of a mole of particles with mass equal to 1 atomic mass unit u is exactly equal to 1 gram. (Note that the atomic mass unit u is defined as 1/12 of the mass of an atom of carbon 12 (2C) and is approximately equal to the mass of a proton.) Using the following values, which are given to 5 significant figures,...

I need help with part B
Explanation:
A mole ratio is the ratio between the amounts in moles of any
two compounds involved in a chemical reaction. The mole ratio can
be determined by examining the coefficients in front of formulas in
a balanced chemical equation.
Step 1: write the balanced chemical
equation.
Sb2S3(s) + 3Fe(s)→2Sb(s) +3FeS(s)
Step 2: calculate the moles of
