If 2 moles of NaClO3 gives you 3 moles of O2, it’s because the mole ratio between NaClO3 : O2 is 2 : 3. Then 12 moles of NaClO3 must give you [12 ÷ 2 then × 3] = 18 moles of O2.
How many grams of NaClO3 were decomposed?
76.68 grams of sodium chlorate are decomposed (2NaClO3->2NaCl +302)
How many grams of NaCl are produced when 30.0 grams of O2 are produced?
How many grams of NaCl are produced when 80.0 grams of O2 are produced? 2 NaClO3 —> 2 NaCl + 3 O2 | Socratic.
How many grams can be produced from moles?
Multiply the resulting number by the number of grams per mole of product to find the mass of product able to be produced by the given amount of reactant. There are 2.1749 moles of NaCl and one mole equals 58.243 grams. 2.1749 × 58.243 = 126.67, so the 50.000 g of Na used in the reaction can create 126.67 g of NaCl.
How many moles of O2 are consumed if 8 moles of H2 are used?
4 moles of O2 will be consumed from 8 moles of H2 when the two substances react to form water.
How many grams of O2 will be produced from 12.00 moles of NaClO3?
Overall, 12 moles of NaClO3 will produce 576 grams of O2.
What mass of O2 is generated?
Each O weights 16 g/mol; O2 has two atoms, thus the molar mass would be 32 g/mol. 0.122399021 mol O2 *(32 g/mol O2) (mol O2 cancels out in the numerator and in the denominator, yielding 3.91679. In the question the mass has two significant figures; thus the mass of O2 released would be 4.0 g (two significant figures).
What kind of reaction is 2 naclo3 → 2 NaCl 3 O2?
Type of Chemical Reaction: For this reaction we have a decomposition reaction.
How many grams are there in 2 moles of NaCl?
Hence mass of 2 moles of NaCl is 117g.
How many moles of oxygen are produced when 2 mol potassium chlorate decomposes?
The reaction will produce 3 moles of oxygen gas for every 2 moles of potassium chlorate that decompose.
How many moles of O2 can be produced from 12 moles KClO3?
How many moles of O2 can be produced by letting 12.00 moles of KClO3 react? The KClO3 / O2 molar ratio is 2/3. 2 mol KClO3 / 3 mol. O2 = 12.00 mol KClO3 / x = 18.00 mol.
How many grams are in a mole of oxygen?
Moles of a Substance and the Molecular Weight
The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.
How do you find the moles of a product formed?
In order to calculate the moles of a product, you must know the mass of the product, and its molar mass (g/mol), which is the mass of one mole of of the product. You then divide the mass of the product by its molar mass.
How many moles are in 6 moles of H2?
Then determine which reactant (N2 or H2) is the limiting reagent. 6 mol of N2 could generate 6•(2/1)= 12 mol of NH3 while 6 mol of H2 can only generate 6•(2/3)= 4 mol (assuming all reactants react).
How many moles of NH3 are produced when 2.1 moles H2 reacts?
How many moles of NH3 are produced when 2.1 mol of H2 reacts? Solution. x = 2,1*2/3 = 1,4 mol.
What is the mole ratio in the following reaction 2co O2 → 2co2 *?
Why the ratio of dioxygen to carbon dioxide is 1:2 on the basis of moles, i.e. on the basis of number of particles .
