The weight of 1 liter of air depends on the composition of the air, the temperature, the pressure, and the gravitational field it is subject to.
As an example, let us assume air of composition:
79 mole% N2 (nitrogen)
20 mole% O2 (oxygen)
1 mole % Ar (argon)
This would give an average molecular weight of
0.79x28.01335 + 0.20x31.9988 + 0.01x39.948 = 28.930 or 28.930 g/mole
At 0 °C and 1 bar pressure 1 mole of gas occupies 22.4 liters, i.e. 22.4 liters/mole
hence we have 28.930/22.4 = 1.29 g/liter
At normal earth gravity this would weigh 0.0127 N (Newtons) or 0.00285 lbf or 0.0456 ounces.
One mole of bromine (Br2) weighs approximately 159.808 grams.
One liter of bromine weighs approximately 3.10 kg.
It means, weigh about 5 grams of NaCl, precisely, to the milligram. I don't really know how to make it much simpler than that. Maybe this will help. 5 grams is 5000 milligrams. The value you get for the sodium chloride you weigh out will probably be between 4900 and 51000 milligrams. Anywhere in that range is fine.
The molecular weight of a chlorine molecule (Cl2) is approximately 70.91 grams per mole. Therefore, one diatomic molecule of chlorine would weigh about 70.91/6.022 x 10^23 grams, which is approximately 1.18 x 10^-22 grams.
The density of bromine is 3.12 g/ml, therefore 10 ml of bromine would weigh 31.2 grams.
1.5 Kilos is the heaviest, but typically the ball would weigh around 800 grams
he much does a liter of rice weigh in grams
How much does 100 ml of vinegar weigh in grams?
80 grams
250 grams
They weigh in grams. Roughly around 20 or so grams
of course 400 grams!!!
2 grams
2 grams weighs 2 grams.
All U.S. nickels weigh 5 grams.
Five saltine crackers typically weigh about 15 grams.
200 grams equates to almost 1/2 of a pound.
