How do you calculate the mass in grams of 4.2 x 1025 NH3?
Molecules of ammonia? Will assume so. 4.2 X 1025 molecules NH3 (1 mole NH3/6.022 X 1023)(17.034 grams/1 mole NH3) = 1188 grams of ammonia ===================( could call it 1200 grams NH3 for significant figure correctness )
How many grams of ammonia contain 1.80 x 1025 atoms of hydrogen?
7,02 g ammonia
How many grams are there in 1.5 x 1025 molecules of CO2?
1100 Grams. or 2.42 pounds.
How many grams is 1.025kg?
1.025 kg is equal to 1025 grams.
How many grams of chlorine gas are in 6.82 x 1024 molecules of chlorine gas?
Chlorine gas (at standard temperature and pressure) consists of diatomic molecules. Therefore, in the specified number of molecules of chlorine gas there are 1.364 X 1025 atoms. The gram atomic mass of chlorine, which by definition consists of Avogadro's Number of atoms, is 35.453. Therefore, the mass of the specified number of molecules of chlorine gas is 35.453 X [(1.364 X 1025)/(6.022 X 1023)] or 803 grams, to the justified number of significant digits.
How many molecules of in 1.26 x 10 3 grams of c2h4?
The gram molecular mass of C2H4 is 28.05. Therefore, 1.26 X 103 grams constitutes (1.26/28.05) X 103 or about 44.9 moles. Each mole contains Avogadro's number of molecules; therefore, 1.26 X 103 grams contains 2.71 X 1025 molecules, to the justified number of significant digits.
How many molecules of carbon dioxide gas are there in 34 moles?
There are approx 2.05*1025 molecules.
How many atoms are in 50.7 grams of hydrogen atoms?
3.05 x 1025
What is the answer if you convert 1.23 1025 Ba atoms to grams of Ba atoms?
123
How many molecules in coffee?
A cup of coffee (200 cm3) contains about 1.5 * 1025 molecules.
What is the amount of molecules of gas in room temperature?
A cubic meter of gas at standard temperature and pressure will have approximately 2.6 x 1025 molecules. This is based on the Avogadro's Number of molecules, (approximately 6.022 x 1023) taking up a volume of around 23 liters. Alternatively, 32 grams of oxygen has Avogadro's number of molecules.
How many molecules are in 7.4 g H'S?
By definition, Avogadro's Number is the number of molecules or formula units in the number of grams corresponding to the gram molecular weight or gram formula unit, and by experiment, Avogadro's Number is about 6.022 X 1023. Therefore, 7.75 X 1025 formula units contains (7.75 X 1025/6.022 X 1023) or 1.29 X 102 moles or formula units, to the justified number of significant digits.
