Answer:
11.647g of water may be produced.
Explanation:
chemistry of the reaction:
2O2 + 2H2 ----> 2H2O + O2
64g + 4g yields 36g of water,
20g + 2g yields 11.647058824g of water
Answer:
25.30 gram
Explanation:
No of moles = given mass / molar mass
No of moles = 63.17/80.06
0.7890 moles
Mass of sulphar = no of moles× molar mass of sulphar
Mass of sulphur = 0.7890×32.065
25.30 gram
