20 grams. Its mass does not change when it changes from a liquid to a gas - only its volume (which is much larger - how much larger depending on the pressure of the gas).
When 2 grams of water is converted from liquid to gas at its boiling point, it requires an input of approximately 2260 joules of energy. Conversely, when 2 grams of steam condenses into liquid water, it releases around 2260 joules of energy.
A typical gas range can weigh anywhere from 150 to 300 pounds, depending on the size and features of the unit.
Octane gas weighs about 6.073 to 6.296 pounds per gallon, depending on its specific gravity and temperature.
An empty drum of AV GAS fuel typically weighs around 20-30 pounds. When full, it can weigh between 300-400 pounds, depending on the size and capacity of the drum.
The weight of a grill can vary depending on its size and material. On average, a standard charcoal grill may weigh around 20-50 pounds, while a larger gas grill can weigh between 50-200 pounds. It's always best to check the manufacturer's specifications for the exact weight of a specific grill model.
In order to figure this out, you must do dimensional analysis. Here it is: 3.0 moles He x 4.0026 grams/ mole He = 12 grams
The weight of the helium gas inside the balloon can be calculated using its molar mass, the Ideal Gas Law, and the given volume. Assuming standard conditions, helium gas has a molar mass of 4 grams per mole. Thus, a 22.4 liter balloon filled with helium gas would weigh approximately 32 grams.

Gasoline is less dense than water, which has a density of 1 kg / liter. Depending on alot of variables, gasoline has a density of 0.71 to 0.77 kg / liter. So to answer your question, 1 liter of gasoline weighs 710 to 770 grams.
When 2 grams of water is converted from liquid to gas at its boiling point, it requires an input of approximately 2260 joules of energy. Conversely, when 2 grams of steam condenses into liquid water, it releases around 2260 joules of energy.

The balanced chemical equation for the reaction between oxygen and hydrogen is2H2 + 02 -> 2H2OThus 2.2 moles of oxygen reacts with 4.4 moles of hydrogen to form 4.4 moles of steam (water in gaseous state).The mass of H2O obtained is thus 4.4 x 18.0 = 79.2g.
Matter might look different after a physical change, but the kind of matter itself does not change. Its particles have not changed. They are just packed together differently.
A typical gas range can weigh anywhere from 150 to 300 pounds, depending on the size and features of the unit.
In chemistry, the outcome of a reaction must have the same mass as the initial state. This means that if you have 32g of oxygen and 4g of hydrogen, you just have to add the numbers to discover the original mass (in this case, 36g).
1 gallon of propane gas weighs 4.2 pounds.
