How many molecules of ethane are present in 0.334 grams of ethane?
mol. mass of ethane = 2x12.01+ 6x1.008= 30.01g/mol # of mole in 0.334 of ethane= 0.334/30.01= 0.01mol
Which reaction shows that the enthalpy of formation of C2H4 is Hf 52.5 kJ mol?
2C(s) + 2H2(g) + 52.5 kJ -> C2H4
How many molecules are contained in 1.20 mol O2?
The number of molecules is 7,2265690284.10e23.
How many molecules are present in 1296 g of dinitrogen pentoxide (N2O5)?
1296 g N2O5 x 1 mol N2O5/108 g x 6.02x10^23 molecules/mole = 7.22x10^24 molecules
How many molecules are in 6.30 mol CO2?

How many grams of ethylene are needed to react with 0.132 mol of H20?
C2H4 + H2O --> C2H5OHReaction balanced at 1:1:1 mole of each compound, so you'll need 0.132 mol C2H4 and this is equal to:0.132 (mol C2H4) * 28 (g/mol C2H4) = 3.696 g C2H4 = 3.70 g C2H4
How many moles are present in 1.21 molecules of HBr?
2.01 mol
How many molecules of sulfur tetrafluoride are present in 2.13 moles of this compound?
There are 1.28x10^24 molecules of SF4. 2.13 mol * 6.022x10^23 molecules/mol = 1.28x10^24 molecules.
What volume will 1.50 mol of C2H4 gas occupy at STP?
1 mole gas = 22.4L 1.5mol C2H4 x 22.4L/mol = 33.6L ethane gas (C2H4)
How many molecules of water can be produced by the reaction of 2.16 mol of oxygen with excess Ethylene.?
C2H4 + 3 O2 --> 2 CO2 + 2 H2OSo 2.16 mol O2 will produce 1.44 mol H2O(and 1.44 mol CO2)because 3:2 = 2.16 : 1.44
How many molecules OS CO2 are present in 51.5 of CO2?
2.65 mol * 64.07 g/mol = 169.79 g
