How many moles of oxygen are there in one mole of hydrogen peroxide?
In one mole of hydrogen peroxide (H2O2), there are two moles of oxygen atoms.
How many moles of oxygen are in one mole of calcium carbonate?
1 mole CaCO3 (3 mole O/1 mole CaCO3) = 3 moles oxygen
How many moles of nitrogen are in 2.5 10 -2 moles of quinine?
Since quinine has a nitrogen atom in its chemical formula, 1 mole of quinine contains 1 mole of nitrogen atoms. Therefore, in 2.5 x 10^-2 moles of quinine, there are also 2.5 x 10^-2 moles of nitrogen atoms.
How many atoms are in 1.38 mole of nitrogen?
1.38 moles of nitrogen equal16,62110876532.1023 atoms; the molecule of nitrogen is diatomic.
What is the mole percentage of oxygen in a mixture of 7grams of nitrogen and 8grams of oxygen is?
To find the mole fraction of oxygen, you first need to calculate the number of moles of each element. The molar mass of nitrogen is 14 g/mol and oxygen is 16 g/mol. Then, divide the moles of oxygen by the total moles of both elements (oxygen + nitrogen) and multiply by 100 to get the mole percentage of oxygen.
How many moles of oxygen are in one mole of P4O10?
There are 10 moles of oxygen in one mole of P4O10. This is because each molecule of P4O10 contains 4 phosphorus atoms and 10 oxygen atoms.
How many moles are there in 12.8grammes of oxygen?
12.8 grams oxygen (1 mole O/16.0 grams) = 0.800 moles of oxygen
In order to get 1 mole of ammonia how many moles of nitrogen is needed?
Each mole of ammonia requires one mole of nitrogen atoms. However, the nitrogen in the air occurs as diatomic molecules; therefore, only one-half mole of molecular nitrogen is required for each mole of ammonia.
What is the empirical formula of a compound that contains 0.20 moles of nitrogen atoms and 0.40 moles of oxygen atoms?
Divide the larger by the smaller mole number. The smaller mole number is assumed to be 1. 0.40/0.20 = 2 As nitrogen is 0.20 moles we have 1 atom of it and 2 atoms of oxygen, so NO2 is the empirical formula (nitrogen dioxide).
How many moles of oxygen are produced from twelve moles of potassium chlorate?
12 moles KClO3 (3 moles O/1 mole KClO3) = 36 moles of oxygen.
When sodium azide is activated in an automobile airbag how many moles of nitrogen are produced if 0.500 mole of sodium azide react?
0,75 moles of nitrogen
How many moles of each element are shown in the formula for H2O?
In one molecule of H2O, there are 2 moles of hydrogen (H) and 1 mole of oxygen (O).
