Question

Tin oxide reacts with hydrogen to produce tin and water how many moles of SnO2 are needed to produce 500.0 g of Sn

Answer 1

Answer:

                        4.21 mol of SnO₂

Explanation:

                      The balance chemical equation for this single replacement reaction is as follow;

                              SnO₂ + 2 H₂ → Sn + 2 H₂O

Step 1: Calculate moles of Sn as:

Moles = Mass / A.Mass

Moles = 500 g / 118.71 g/mol

Moles = 4.21 moles

Step 2: Find out moles of SnO₂ as,

According to balance equation,

                      1 mole of Sn is produced by  =  1 mole of SnO₂

So,

               4.21 moles of Sn will be produced by  =  X moles of SnO₂

Solving for X,

                      X =  1 mol × 4.21 mol / 1 mol

                       X  =  4.21 mol of SnO₂
