Which has more mass a mole of potassium or a mole of sodium?
A mole of potassium. Sodium weighs 22.990 g/mol while potassium weighs 39.068 g/mol.
How many moles in potassium bicarbonate?
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.
Calculate the mass in 3.3 moles of potassium sulphide?
To calculate the mass of 3.3 moles of potassium sulfide, you would first determine the molar mass of K2S. The molar mass of potassium (K) is 39.1 g/mol and sulfur (S) is 32.1 g/mol. Therefore, the molar mass of K2S is 39.1*2 + 32.1 = 110.3 g/mol. Multiply this molar mass by 3.3 moles to find the mass.
What is the molar mass of potassium sorbate?
I believe it is 174.2592, but I could be mistaken. I believe it is 174.2592, but I could be mistaken. KNO3 has a molar mass of 101.10303
What is the percentage of iodine in potassium iodide?
The percentage of iodine in potassium iodide can be calculated using the formula: (molar mass of iodine / molar mass of potassium iodide) x 100. The molar mass of iodine is approximately 126.9 g/mol, and the molar mass of potassium iodide is approximately 166 g/mol. Therefore, the percentage of iodine in potassium iodide is (126.9 / 166) x 100 = 76.5%.
What mass of potassium ions is present 25.0 mL of 0.50 M K2SO4 in grams?
To find the mass of potassium ions in 25.0 mL of 0.50 M K2SO4, first calculate the number of moles of K+ ions present. Since there are 2 K+ ions per K2SO4 unit, you have 0.50 moles/L * 0.025 L * 2 K+ ions/molecule. Finally, multiply the number of moles by the molar mass of potassium (39.10 g/mol) to find the mass in grams. The calculation would be: 0.50 mol/L * 0.025 L * 2 mol K+/mol K2SO4 * 39.10 g/mol K = 0.98 grams of potassium ions.
How many moles of K2SO4 are in 15.0 grams of K2SO4?
To find the number of moles of K2SO4 in 15.0 grams, first calculate the molar mass of K2SO4 (K: 39.10 g/mol, S: 32.07 g/mol, O: 16.00 g/mol). Molar mass of K2SO4 = 2(39.10) + 32.07 + 4(16.00) = 174.26 g/mol Now, divide the given mass by the molar mass to find the number of moles: 15.0 g / 174.26 g/mol = 0.086 moles of K2SO4
How many moles are there in 5 grams of potassium sulfate?
To find the number of moles in 5 grams of potassium sulfate (K2SO4), first calculate the molar mass of K2SO4 by adding the atomic masses of potassium (K), sulfur (S), and four oxygen (O) atoms. Then, divide the given mass (5 grams) by the molar mass of K2SO4 to get the number of moles.
What is the mass of 5 moles of Potassium Sulphate?
The molar mass of Potassium Sulphate (K2SO4) is 174.26 g/mol. Therefore, the mass of 5 moles of Potassium Sulphate would be 5 moles x 174.26 g/mol = 871.3 grams.
Why is it difficult to identify potassium ions when sodium ions are present?
It is difficult to identify potassium ions when sodium ions are present because they have similar chemical properties and ionization energies, making them behave similarly in chemical reactions and spectroscopic techniques. Additionally, their atomic masses are close, which can lead to overlapping peaks in analytical techniques such as mass spectrometry or atomic absorption spectroscopy.
Molar mass of k2so4?
The molar mass of K2SO4 (potassium sulfate) is calculated by adding the atomic masses of the elements in the compound. The atomic mass of potassium (K) is about 39.10 g/mol, sulfur (S) is about 32.06 g/mol, and oxygen (O) is about 16.00 g/mol. Adding these together gives a molar mass of approximately 174.26 g/mol.
If potassium has a mass of 39.1 amu and chloride has a mass of 35.45 amu which is the mass of potassium chloride when these two ions are combined?
The molar mass of potassium chloride is 74,5513.
Molecular mass of sulphuric acid and potassium nitrate?

Calculate the molar mass of K2SO4?
174.259 g/mol
How many potassium atoms are present in .01456 grams of potassium?
To calculate the number of potassium atoms, you first need to convert the mass of potassium to moles using the molar mass of potassium (39.10 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of potassium atoms present in the given mass.
What mass of K2CO3 is needed to prepare 200 mL of a solution having a potassium ion concentration of 0.150 M?
To calculate the mass of K2CO3 needed, first convert 200 mL to liters (0.2 L). Then, determine the moles of potassium ions needed using the concentration (0.150 M) and volume (0.2 L) of the solution. Since each formula unit of K2CO3 contains 2 moles of potassium ions, you can then calculate the mass of K2CO3 needed using its molar mass.
