How many moles are in 454 grams in sodium?
atomic waight of hydrogen = 1.0079 weight of one mole of hydrogen = its atomic mass in grams(just like all elements). therefore 454g/1.0079g = 450.4 moles of hydrogen.
How many moles are there in 34.02 g of hydrogen peroxide?
You need to provide the element or molecule name in order to determine the number of moles from the mass that you use. To calculate moles from grams from the given information, it's 34g / (g/mol of specific element or molecule) = mol of specific element or molecule.
How many moles of molecules are there in 250g of hydrogen nitrate?
Hydrogen nitrate has a mass of 63.01 g/mol. In order to find the number of moles you divide the grams by the molar mass. 250/63.01 = 3.96 mol.
Convert 1.3 moles of calcium to grams?
52.1grams. moles = mass (in grams)/RMM (relative molecular mass) 1.3 moles = mass (in grams)/ 40.078 mass = 40.078 x 1.3 = 52.1grams
How many moles of barium are present in a sample having a mass of 22.3 grams?
# of moles = grams of substance / molar mass of substance molar mass of Barium =137.33 grams/mole #moles of Barium = 22.3 grams/ 137.33 grams/mole = 0.162382582 moles
How many moles are in 454 grams in sodium?
atomic waight of hydrogen = 1.0079 weight of one mole of hydrogen = its atomic mass in grams(just like all elements). therefore 454g/1.0079g = 450.4 moles of hydrogen.
How many molecules are there in 6.802 grams of hydrogen peroxide?
The molecular mass of H2O2 is 2(1.0) + 2(16.0) = 34.0Amount of H2O2 = 6.802/34.0 = 0.200mol So there are 0.200 moles of H2O2 moles. To get the exact number, multiply this by the Avogadro's constant.
How many moles of hydrigen are present in a 2 grams sample of hydrogen gas?
Mass (g) = Mr * Moles If you rearrange it, you get Moles = Mass/Mr Working with a 2dp periodic table you get: Moles = 2/1.01 =1.98 There are 1.98 moles of hydrogen in 2g of H2 gas.
How do you find moles of hydrogen?
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance
How many grams is 0.5 moles of sodium bicarbonate?
The molar mass of sodium hydrogen carbonate is 84 grams per mole, therefore 0.5 moles of it weighs 42 grams.
How many grams of water could be made from 5.0 mol H2 and 3.0 mol O2?
The formula for Oxygen gas is O2, and the formula for water is H2O. Each molecule of Oxygen gas can produce 2 molecules of water (with enough Hydrogen, of course). So, 2.5 moles of Oxygen gas would be required to produce 5.0 moles of water.
How many moles are there in 34.02 g of hydrogen peroxide?
You need to provide the element or molecule name in order to determine the number of moles from the mass that you use. To calculate moles from grams from the given information, it's 34g / (g/mol of specific element or molecule) = mol of specific element or molecule.
How many moles of molecules are there in 250g of hydrogen nitrate?
Hydrogen nitrate has a mass of 63.01 g/mol. In order to find the number of moles you divide the grams by the molar mass. 250/63.01 = 3.96 mol.
How many moles are in 75.00 grams of hydrogen?
How many hydrogen atoms are in 35.0 grams of hydrogen gas?
What is the mass of 7.35 moles of boron trihydride?
This mass is 101,6505 g.The atomic masses of hydrogen and boron are 11 and 1 respectively. The relative molecular mass of the compound is 14. Therefore the mass of 7.35 moles is approximately 102.9 grams.
Convert 1.3 moles of calcium to grams?
52.1grams. moles = mass (in grams)/RMM (relative molecular mass) 1.3 moles = mass (in grams)/ 40.078 mass = 40.078 x 1.3 = 52.1grams
How many moles of barium are present in a sample having a mass of 22.3 grams?
# of moles = grams of substance / molar mass of substance molar mass of Barium =137.33 grams/mole #moles of Barium = 22.3 grams/ 137.33 grams/mole = 0.162382582 moles
