What is the mass of 0.561 mol of the element potassium?
40*0.561=22.44g
What is the atomic weight for the element potassium?
The standard of atomic weight 39.0983 +/- 0.0001 u
What is molecular mass of potassium in potassium chloride?
Since potassium chloride has the formula KCl and the mass of the lost electron from neutral potassium is negligible compared with the mass of the protons and neutrons in the potassium atom nucleus, the molecular mass of potassium in this compound is the same as the atomic mass of potassium, 39.098.
What is the mass of 1 mol of rubidium?
According to the periodic table, the atomic mass of rubidium, Rb is 85.5. This is numerically equal to the molar mass in g/mol. Therefore the mass of 1 mol of Rb is 85.5g.Mass of 1 mol means the molar mass of the element. Molar mass of Rubidium is 85.47 gmol-1. Rb is in the 1st group.

What is the molar mass of krypton?
There are 39.0983 grams in one mole of K (potassium). a mole is a number. you cannot ask how many moles are in potassium. but you may ask how many moles of a certain substance are in potassium.
How do you calculate the theoretical mass percentage of oxygen in potassium chlorate?
I believe it is: %O=mass of 3 mol of O / mass of 1 mol of potassium chlorate *100% If you measured it: %O=mass of oxygen lost / mass of potassium chlorate *100%
What is molecular mass of potassium in potassium chloride?
Since potassium chloride has the formula KCl and the mass of the lost electron from neutral potassium is negligible compared with the mass of the protons and neutrons in the potassium atom nucleus, the molecular mass of potassium in this compound is the same as the atomic mass of potassium, 39.098.
What is the mass of 7.111 mol of potassium sulfide?
784.1g
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.
What is the mass of 1.6 mol of the element?
sulfur
What is the molar mass of KOH?
molar mass is the mass of one mole of a substance. A mole is an amount, refers to Avogadros number which is 6.022 x 1023. a mole of atoms is that many atoms. therefore the molar mass of potassium hydroxide KOH is the mass of that many molecules of KOH. On the periodic table the mass number for each element is molar, so all you need to do is add together the molar mass of each element in the compound. Molar mass of potassium (K) is 39 Molar mass of oxygen (O) is 16 Molar mass of hydrogen (H) is 1 There is one of each of these elements in a molecule of potassium hydroxide therefore the molar mass = 39 + 16 + 1 = 56
How many moles are in 282.1g of potassium bisulfate?
The formula for potassium bisulfate is KHSO4. Using the atomic weights on the periodic table for each element, the molar mass of KHSO4 is 136.1688g/mol. Therefore, 1 mol KHSO4 = 136.1688g 282.1g KHSO4 x (1mol KHSO4/136.1688g KHSO4)= 2.027 mol KHSO4
