if you have 9.50x10^25 molecules of KClO3 how many grams of KCl and O2 will you get? The balanced equation is 2KClO3 = 2KCl + 3O2
molsKClO3 = 9.50E25/6.02E23 = ?
Convert mol KClO3 to mols mols KCl and mols O2 using the coefficients in the balanced equation.
Then convert mols KCl to g. g = mols x molar mass
Similarly, g O2 = mols x molar mass.
To find the number of grams of KCl and O2 produced from 9.50x10^25 molecules of KClO3, you can follow these steps:
Step 1: Calculate the number of moles of KClO3:
To convert from molecules to moles, you need to divide the given number of molecules by Avogadro's number (6.022x10^23 molecules/mol):
Number of moles of KClO3 = (9.50x10^25 molecules) / (6.022x10^23 molecules/mol)
Step 2: Use the balanced equation to determine the mole ratios between KClO3, KCl, and O2:
According to the balanced equation, 2 moles of KClO3 produce 2 moles of KCl and 3 moles of O2. This means that the ratio of moles is 2:2:3 between KClO3, KCl, and O2, respectively.
Step 3: Calculate the number of moles of KCl and O2:
Number of moles of KCl = Number of moles of KClO3 x (2 moles of KCl / 2 moles of KClO3)
Number of moles of O2 = Number of moles of KClO3 x (3 moles of O2 / 2 moles of KClO3)
Step 4: Convert the number of moles to grams using the molar mass:
The molar mass of KCl is 74.55 g/mol, and the molar mass of O2 is 32.00 g/mol. Multiply the number of moles by the molar mass to get the mass in grams:
Mass of KCl = Number of moles of KCl x molar mass of KCl
Mass of O2 = Number of moles of O2 x molar mass of O2
By following these steps, you can obtain the mass of KCl and O2 in grams from the given number of molecules of KClO3.
