How much energy is released when 42.5 of water freezes?
You have 42.5 g of water. 42.5g H20 / 18.02 g H2O (2.358 moles H2O)*(6.02 Kj/1mole H2O) = 14.1981 Kj =14.2 kJ
How much water vapor is produce by propane on combustion?
Calculate the mass in grams of water vapor produced if 3.11 moles of propane is burned
How much hydrogen would be required to produce 7.5 mol of water?
3,75 moles hydrogen
How much C4H10 would you need to create 20 ml of water in a combustion?
Pure combustion of butane has the reaction 2 C4H10 + 13 O2 equals8 CO2 + 10 H2O. This means that every mole of butane produces 5 moles of water. 20 ml of water equals 1.11 moles, so .222 moles of butane are needed, or 5.17 liters.
How much water must be mixed with concentrated hydrochloric acid to prapare 50cm3 of 6m hcl solution?
50mL minus the volume of 0.3 moles pure HCl is how much water is necessary. Be sure to add acid to water never water to acid.
How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
Do moles drink?
yes moles do drin water but not much
How much does 4.04 moles of water weigh?
72.8grams
How would you find out how much 12.4 moles of water weigh?
Multiply moles by molecular mass of water (18), gives you 223.8g. Remember this formula: Number of moles = mass / molecular mass
Does baking soda and water sting on moles?
Yes,but not too much...
How do you calculate how much energy in kJ do 3.0 moles of photons all with a wavelength of 655 nm contain?
The energy is 18,263.10e4 joules.
How much energy is released when 42.5 of water freezes?
You have 42.5 g of water. 42.5g H20 / 18.02 g H2O (2.358 moles H2O)*(6.02 Kj/1mole H2O) = 14.1981 Kj =14.2 kJ
For the reaction 2H2 plus O2 equals 2H2O how much water is produced when 2.5 moles of hydrogen react completely How do you do the problem?
2H2 + O2 ---------------> 2H2O for every 2 moles of hydrogen that reacts, 2 moles of water are produced, thus a 1:1 ratio of water produced to hydrogen reacted. So:- 2.5 moles of hydrogen reacted will produce 2.5 moles of water
How much energy in kJ do 3.0 moles of photons all with a wavelength of 655 nm contain?
548kJ
How much energy is absorbed when 23.1 moles of water vaporize?
540 calories per gram is absorbed when water vaporizes at its boiling point. Called the latent heat of vaporization. 540 x 23.1 x 18 = 224532 calories
How much water vapor is produce by propane on combustion?
Calculate the mass in grams of water vapor produced if 3.11 moles of propane is burned
How much does 10 moles of water weigh?
As the molar mass of water is 18 g/mol (1*2 H + 16 O) 10 moles*18 g/mole=180 grams.
