How many moles of water molecules h2o are present in a 27 rams sample of water?
Divide mass of 27 g H2O by its molar mass of 18.0 g.mol−1 H2O and you get the number of moles: 1.5 mole H2O
How many moles of water molecules H2O are present in a 27 gram sample of water?
There are 1.5 moles water in 27 grams
How many GRAMS of hydrogen are present in 2.08 moles of water?
2.08 moles H2O (2 moles H/1 mole H2O)(1.008 grams H/1 mole H) = 4.19 grams of hydrogen ===================
How many moles of Hydrogen are im 2.5 moles of H2O?
2.5 moles H2O (2 moles H/1 mole H2O) = 5 moles of hydrogen
How many moles are in 8g of H2O?
8g / 18 g/mol H2O = .44 moles H2O
How many moles of H2O are present in 150.0G of H2O?
The answer is 8,33 moles.
How many moles of Helium are present in 5.66 moles of H2O?
H2O or water doesn't have any helium in it.
How many moles of water molecules h2o are present in a 27 rams sample of water?
Divide mass of 27 g H2O by its molar mass of 18.0 g.mol−1 H2O and you get the number of moles: 1.5 mole H2O
How many moles of water molecules H2O are present in a 27 gram sample of water?
There are 1.5 moles water in 27 grams
How many moles of H2O is 7.038 grams of H2O?
The answer is 0,44 moles.
How many GRAMS of hydrogen are present in 2.08 moles of water?
2.08 moles H2O (2 moles H/1 mole H2O)(1.008 grams H/1 mole H) = 4.19 grams of hydrogen ===================
How many moles of Hydrogen are im 2.5 moles of H2O?
2.5 moles H2O (2 moles H/1 mole H2O) = 5 moles of hydrogen
How many moles are in 8g of H2O?
8g / 18 g/mol H2O = .44 moles H2O
How many gram are in 3.0 moles of H2O?
3.0 moles of H2O have 54 g.
How many hydrogen atoms are present in 3.65 grams of water?
3.65 grams of water is equal to .203 moles of H2O. This means there is also .203 moles of H2 present, or .408 grams.
How many moles of H2O are produced when 0.468 mol of octane is burned?
It forms H2O when burned.There are 3.744 moles of H2O after burned.
How many moles of H2 are needed to produce 8.25 mole of H2O?
2H2 + O2 --> 2H2OFor every 2 moles of H2, 2 moles of H2O will be produced (i.e., a 1:1 ratio). So to produce 8.25 moles of H2O you will also need 8.25 moles of H2
