Potassium (chemical symbol K) has atomic number 39.1.
Amount of K in 449g sample = 449/39.1 = 11.5mol
There are 11.5 moles of potassium in a 449g sample.
1,5 moles of potassium carbonate have 276,41 g.
Well, darling, if you want to get technical, the molar mass of potassium is approximately 39.10 g/mol. So, if you have 156.4 g of potassium, you simply divide the given mass by the molar mass to find that you have about 4 moles of potassium. But hey, who's counting?
To calculate the grams of potassium bromite in 0.280 moles, you would multiply the number of moles by the molar mass of KBrO2, which is 119 g/mol. Therefore, 0.280 moles of KBrO2 would be 0.280 moles * 119 g/mol = 33.32 grams.
To calculate the number of moles of potassium chloride in a 100.0g sample, you need to divide the mass of the sample by the molar mass of potassium chloride. The molar mass of potassium chloride is approximately 74.55 g/mol. Therefore, 100.0g ÷ 74.55 g/mol = approximately 1.34 moles of potassium chloride in the sample.
To find the number of grams in 3.3 moles of potassium sulfide (K2S), you need to calculate the molar mass of K2S, which is 110.26 g/mol. Then, you can multiply the molar mass by the number of moles to get the grams. In this case, 3.3 moles x 110.26 g/mol = 363.858 g.
To determine the number of moles of potassium in 449 g, you need to divide the mass (449 g) by the molar mass of potassium (39.1 g/mol). This calculation would give you the number of moles of potassium in 449 g.
To find the number of moles, you first need to calculate the molar mass of potassium (39.10 g/mol). Then, divide the given mass (449g) by the molar mass to get the number of moles. In this case, 449g of potassium would contain approximately 11.5 moles.
12 g of potassium is equivalent to 0,307 moles.
34,7 moles of potassium 1 356,7 g.
242.594 g
0.4g/mol
1,5 moles of potassium carbonate have 276,41 g.
Well, darling, if you want to get technical, the molar mass of potassium is approximately 39.10 g/mol. So, if you have 156.4 g of potassium, you simply divide the given mass by the molar mass to find that you have about 4 moles of potassium. But hey, who's counting?
To calculate the grams of potassium bromite in 0.280 moles, you would multiply the number of moles by the molar mass of KBrO2, which is 119 g/mol. Therefore, 0.280 moles of KBrO2 would be 0.280 moles * 119 g/mol = 33.32 grams.
To calculate the grams of potassium permanganate in 2.20 moles, you would need to know the molar mass of potassium permanganate. The molar mass of potassium permanganate (KMnO4) is about 158.034 g/mol. So, 2.20 moles of KMnO4 is equal to 2.20 moles x 158.034 g/mol = 347.67 grams of potassium permanganate.
The answer is 224,24 g oxygen.
To calculate the number of moles of potassium chloride in a 100.0g sample, you need to divide the mass of the sample by the molar mass of potassium chloride. The molar mass of potassium chloride is approximately 74.55 g/mol. Therefore, 100.0g ÷ 74.55 g/mol = approximately 1.34 moles of potassium chloride in the sample.
