How many grams of h20 will be produced?
18 g
How many grams of oxygen are required to produce 358.5 grams zno?
Answer: 35.24 grams of are required to produce the given amount of Zinc oxide. So, 4.405 moles of zinc oxide is produced from = of oxygen.
How many grams of ZnO are produced?
81.3794 grams
How many moles of carbon dioxide are produced when 19.3 mol of propane gas is burned?
57.9 mole
How many moles of carbon dioxide are produced when 851g of propane C3H8 gas is burned in excess oxygen?
This tells you that when 1 mole of propane undergoes combustion, 3 moles of carbon dioxide are produced.
How many moles of carbon dioxide are produced when 10.4 mol of propane gas is burned in excess oxygen the equation for the combustion of propane is?
The formula of propane is C3H8. The reaction equation is C3H8 + 5O2 = 3CO2 + 4H2O. So the ratio of mol number of propane and CO2 is 1:3. So the CO2 has 10.4*3=31.2 mol.

What is the SI base unit used to measure the amount of a substance?
The SI unit of concentration (of amount of substance) is the mole per cubic meter (mol/m3).
How many moles are in 68 grams of copper II hydroxide?
There are 0.70 moles of Cu(OH)2 .
What is the mass of gas?
The molecular weight (molar mass) of any gas is the mass of one particle of that gas multiplied by Avogadro’s number (6.02 x 1023). Knowing the molar mass of an element or compound can help us stoichiometrically balance a reaction equation.
Does temperature and pressure change molar mass?
Molar Mass of Gases and Gas Mixtures The molar volumes of all gases are the same when measured at the same temperature and pressure (22.4 L at STP), but the molar masses of different gases will almost always vary.
Do gases have mass?
Gases have mass. The space between gas particles is empty.
How do you show the mass of a gas?
Place a can of compressed gas on a scale and check its mass. Ask students whether it will weigh more, less, or the same if you squeeze the trigger and let some gas out. Shoot gas out of the can for a few seconds and then place the can back on the scale.
When a gas is compressed what happens to the temperature?
As the gas is compressed, the work done on it shows up as increased internal energy, which must be transferred to the surroundings to keep the temperature constant. At constant temperature, the gas law becomes P∝V−1; Adiabatic: No heat is transferred between the gas and its surroundings as it is compressed / does work.
