how many grams of water can be produced the combination of 10 grams of oxygen and 8 grams of hydrogen

Mass =  11.16 g

Explanation:

Given data:

Mass of hydrogen = 8 g

Mass of oxygen = 10 g

Mass of water produced = ?

Solution:

Chemical equation:

2H₂ + O₂         →      2H₂O

Number of moles of hydrogen:

Number of moles = mass / molar mass

Number of moles = 8 g/ 2 g/mol

Number of moles = 4 mol

Number of moles of oxygen:

Number of moles = mass / molar mass

Number of moles = 10 g/ 32 g/mol

Number of moles = 0.31 mol

now we will compare the moles of hydrogen and oxygen with water.

                   O₂          :           H₂O

                    1            :             2

                  0.31         :            2/1×0.31 = 0.62

                  H₂           :            H₂O

                    2            :              2

                     4            :              4

Number of moles of water formed by oxygen are less this it will act as limiting reactant.

Mass of water:

Mass = number of moles × molar mass

Mass = 0.62 mol × 18 g/mol

Mass =  11.16 g

i'm pretty sure its b i might be wrong though!

i wish i could but this one is weird give me abc and i can solve it.
