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.
This problem requires potassium's atomic mass. Take the number of moles multiply it by the atomic mass. Going from grams to moles, you would divide instead.
3.00 mole K × (39.1 grams) = 117.3 grams K
This problem requires potassium's atomic mass. Take the number of moles multiply it by the atomic mass. Going from grams to moles, you would divide instead.
3.00 mole K
There are 0.246 moles in 10g of potassium.
1 mole Na = 22.990g Na
10g Na = 1mol Na/22.990g Na = 0.4 mole Na
3.3 moles of potassium sulfide is equal to 363,86 g.
300 g of potassium is equal to 7,67 moles.
Mass in grams = no of moles x molecular mass. So, mass in grams = 5.2x 56 = 291.2g
25,3 moles of potassium sulfate hva a mass of 4,4409 kg.
45/94.2 is 0.4777 moles
The molecular weight of potassium nitrate (KNO3) is 101.1 grams/mole.K = 39.1 + N = 14.0 + O = 3*16.0 = 101.1Now divide 6.5 by 101.1 to calculate # of moles => 0.064 moles KNO3
16 grams of oxygen how many moles is 0,5 moles.
242.594 g
300 g of calcium sulfide (CaS) is equal to 4,158 moles.
34,7 moles of potassium 1 356,7 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.
Mass in grams = no of moles x molecular mass. So, mass in grams = 5.2x 56 = 291.2g
45/94.2 is 0.4777 moles
224 g are in two moles of potassium dichromate.
25,3 moles of potassium sulfate hva a mass of 4,4409 kg.
3.99 or 4
About 0.013
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.
224 grams of Oxygen will be in 2 moles of Potassium dichromate.
