How many grams of potasium carbonate are in 1.5 moles of this substance?
1,5 moles of potassium carbonate have 276,41 g.
How many grams of potassium bromite (KBrO2) are there in 0.280 moles?
This mass is 42,28 g.
How many moles of potassium are in 156.4 g of potassium?
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
How many grams of potassium chloride are produced if 25 grams of potassium chlorate decompose into potassium chloride and oxygen?
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
How much does 35.1 moles of potassium weigh?
The molar mass of potassium (K) is approximately 39.1 g/mol. Using this molar mass, we can calculate the weight of 35.1 moles of potassium by multiplying the molar mass by the number of moles. Therefore, 35.1 moles of potassium would weigh approximately 1371.41 grams.
How many moles of potassium are contained in 449 g of potassium?
449 g K x 1 mole K/39 g K = 11.5 moles (3 sig figs)
How many moles of potassium are contained in 449g of potassium?
449 (g K) / 39.1 (g/mol K) = 11.5 mol K
How many moles are in 12g of potassium?
12 g of potassium is equivalent to 0,307 moles.
How many grams are in 34.7 moles of potassium?
34,7 moles of potassium 1 356,7 g.
How many grams of oxygen wil be in two moles of potassium dichromate?
In potassium dichromate (K2Cr2O7), there are 7 oxygen atoms per molecule. Therefore, two moles of K2Cr2O7 would contain 14 moles of oxygen atoms. Each mole of oxygen atoms has a molar mass of approximately 16 grams, so there would be 224 grams of oxygen in two moles of potassium dichromate.
How many grams are in 2.2 moles of potassium sulfide?
242.594 g
How many moles are found in 15.6 g of potassium?
