How many grams of CH4 are needed to react completely with 6.4 grams of O2? CH4 + O2 arrow CO2 + H2O ___NH_{3} + ___O_{2} \rightarrow ___N_{2} + ___H_{2}O a. 20 moles of NH_{3} are needed to produce ___ moles of H_{2}O. b, How many moles of ...
Answer to: How do you find the number of moles of a gas if the pressure is 1.00 atm, the volume is 800 L, the temperature is 325 K, and KE = 4.05...
2. Calculate the heat. Given that delta H = -91 kJ 3. Calculate K my solution : 3H2 + N2 ---> 2NH3 I 3 9 C -3x -x +2x E 3-3x 9-x 2x then 2x/(2x+12−3x−x) = 1/2 then x = 2 but it's impossible because moles of H2 after equilibrium will be -3 so...
Find out the amount of moles of a certain substance knowing that the amount of units of said substance is 1.8×10231.8×1023. I have to find how many moles of carbon, hydrogen, and oxygen that amounts to. The number 1.8×10231.8×1023 was calculated in a previous question where...
How to Find the Moles of HNO3 How to Make Stoichiometry Easy What Conversion Factor is Present in Almost All Stoichiometry... What Is the Number Written to the Left of the Chemical... How is the Equilibrium Constant of a Reaction Determined?
How to Find Molarity As long as you have a way of measuring the mass of a solute, you can calculate its molarity by measuring the volume of the solution. Be careful here, because molarity is always expressed as moles/liter, so if you measure volume in any other units, you have to con...
grams of sample = (molar mass) x (moles) Problem Find the number of grams in 0.700 moles of hydrogen peroxide, H2O2. Solution Calculate the molar mass by multiplying the number of atoms of each element in the compound (its subscript) times the atomic mass of the element from the periodic...
Researchers haven’t found a range that is too low for triglycerides, and having a low triglyceride level is good. If your numbers are consistently very low, your doctor may want to find out why. Very low triglycerides could be caused by: ...
