Atomic mass of potassium, K = 39.1
Amount of potassium is 156.4g sample = 156.4/39.1 = 4.00mol
There are 4 moles of potassium in 156.4 grams of potassium.
224 grams of Oxygen will be in 2 moles of Potassium dichromate.
224 grams of oxygen are in 2 moles of potassium dichromate.
34,7 moles of potassium 1 356,7 g.
The formula for potassium dichromate is KËÃCrËÃOËÈ. How many grams of oxygen will be in 2 moles of potassium dichromate?
You did not describe the amount of potassium bicarbonate amount in grams in your question. But if you are about 1 gram of potassium bicarbonate it will be 0.0099 moles in one gram of potassium bicarbonate. 0.0199 moles in 2 grams of potassium bicarbonate.
3.3 moles of potassium sulfide is equal to 363,86 g.
50 g potassium iodide is equivalent to 0,3 moles.
There are 39.0983 grams in one mole of K (potassium). a mole is a number. you cannot ask how many moles are in potassium. but you may ask how many moles of a certain substance are in potassium.
224 g are in two moles of potassium dichromate.
25,3 moles of potassium sulfate hva a mass of 4,4409 kg.
50 g potassium chloride is equivalent to 0,67 moles.
45/94.2 is 0.4777 moles
In one mole of potassium dichromate, there seven moles of oxygen. This means in two moles of K2Cr2O7, there are 14 moles of O, or 7 Moles of O2, which equals 224 grams.
The molar mass of potassium is 39,0983(1) g.
This mass is 347,67 for KMnO4.
1,5 moles of potassium carbonate have 276,41 g.
Potassium has atomic number 39.1.Amount of K in 284g sample = 284/39.1 = 7.26molThere are 7.26 moles of potassium in a 284g sample.
The answer is 224,24 g oxygen.
Structure for this is K2Cr2O7. there are 14 moles of O in 2 moles.
Molecular weight of potassium (K): 39.1 g/mole...Just divide 156 by the molecular weight to get moles:156/39.1 = 3.99 moles K
You have2KClO3 ==> 2KCl + 3O2 as the balanced equation 25 g KClO3 x 1 mole/123 g = 0.20 moles moles KCl formed = 0.20 moles KClO3 x 2 moles KCl/2 moles KClO3 = 0.20 moles KCl formed grams KCl = 0.20 moles x 74.5 g/mole = 14.9 g = 15 grams of KCl formed
The atomic mass of Potassium is 39 and that of Sulfur 32. The formula for Potassium Sulfide is K2S therefore the molecular weight of Potassium Sulfide is (39 * 2) + 32 = 110. Therefore one mole of Potassium Sulfide weighs 110 grams. Therefore 3.3 moles of Potassium Sulfide weigh 110 * 3.3 = 363 grams.
The atomic mass of potassium, K is 39.1. Amount of potassium = mass of sample / atomic mass= 2.25/39.1 = 0.0575mol
In 48 g of potassium are 1,228 moles.
Atomic mass of potassium, K = 39.1 Amount of K in 2.0g sample = 2.0/39.1 = 0.0512mol
