How many grams of oxygen wil be in two moles of potassium dichromate?
224 g are in two moles of potassium dichromate.
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
