The answer is 8,33 moles.
The answer is 0,44 moles.
It forms H2O when burned.There are 3.744 moles of H2O after burned.
2.95 mole H2O (2 moles H/1 mole H2O) = 5.90 moles hydrogen ------------------------------
1.54 moles H2O (18.016 grams/1 mol H2O ) =27.7 grams
21
2.5 moles H2O (2 moles H/1 mole H2O) = 5 moles of hydrogen
The answer is 8,33 moles.
The answer is 0,44 moles.
8g / 18 g/mol H2O = .44 moles H2O
It forms H2O when burned.There are 3.744 moles of H2O after burned.
3.0 moles of H2O have 54 g.
Using the molar mass of nh3, we find that we have 2.5 moles of nh3. Since 3 moles of h2o are produced per 2 moles of nh3, we see that we will produce 3.75 moles of h2o. This is equivalent to around 3.79 g.
2.95 mole H2O (2 moles H/1 mole H2O) = 5.90 moles hydrogen ------------------------------
According to this balanced equation:Na2O + H2O --> 2NaOH42 moles Na2O react with 42 moles H2O
H2O or water doesn't have any helium in it.
The mass of 2,1 moles H2O is 37,8 g.
