25,3 moles of potassium sulfate hva a mass of 4,4409 kg.
4,12 grams aluminum sulfate is equivalent to 0,012 moles (for the anhydrous salt).
Molarity = moles of solute/Liters of solution ( 100 mL = 0.1 Liters)Moles of solute (K2SO4) = Liters of solution * MolarityMoles K2SO4 = 0.1 Liters * 0.1 M= 0.01 moles K2SO4 (174.27 grams/1 mole K2SO4)= 1.7 grams potassium sulfate=======================Add that many grams potassium sulfate to your 100 mL.
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.
Potassium sulfate has a molar mass of 174.259 grams per mole. In15 grams there are then 86.1 millimoles of K2SO4.
The formula for potassium dichromate is KËÃCrËÃOËÈ. How many grams of oxygen will be in 2 moles of potassium dichromate?
The answer is 32,4.10e23.
1,11 moles of anhydrous manganese sulfate contain 167,61 g.
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.
You have to use the equationnumber of moles = mass/Molar massn = 5/(39.1+32.1+64)n = 5/135.2number of moles = 0.04:)
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.
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.
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.
3.6 moles N2SO4 (142.05 grams/1 mole Na2SO4) = 511.38 grams Na2SO4 ==================( you do significant figures )
The molar mass of potassium is 39,0983(1) g.
A cation is the positive ion part of the ionic compound. That means for every mole of potassium sulfate, there are two moles of the cation potassium. So there are 2.90 moles of K+.
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.
