What is the number of moles of h2o produced from 221 grams of sno2?

2.932 moles

Assuming the equation for the reaction in question is;

SnO₂(s) + 2H₂(g) → Sn(s) + 2H₂O(l)

Then we can answer the question given;

We are given;

We need to calculate the number of moles of H₂O produced;

To calculate the number of moles we divide mass of of a compound by its molar mass.

Molar mass of SnO₂ = 150.71 g/mol

Therefore;

Number of moles =221 g ÷ 150.71 g/mol

                             = 1.466 moles

From the equation, 1 mole of SnO₂ reacts to produce 2 moles of H₂O

Thus, the mole ratio of SnO₂ : H₂O is 1 : 2

Hence; Moles of H₂O = Moles of SnO₂ × 2

                                    = 1.466 moles × 2

                                    = 2.932 moles

Therefore, 2.932 moles of H₂O are produced.

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
