How many moles are contained in 1.23 grams of krypton?

To determine the number of moles in 1.23 grams of krypton, first find the molar mass of krypton (Kr), which is approximately 83.80 g/mol. Then, divide the given mass (1.23 g) by the molar mass of krypton to find the number of moles. In this case, 1.23 g / 83.80 g/mol ≈ 0.015 moles of krypton.


What is the number of moles in 607 g krypton?

To find the number of moles in 607 g of krypton, divide the given mass by the molar mass of krypton. The molar mass of krypton is approximately 83.80 g/mol. So, 607 g ÷ 83.80 g/mol ≈ 7.25 moles of krypton.


Does one mole of krypton atoms has a mass of 41.90g?

What volume will 0.405 g of krypton gas occupy at STP?

First we need the moles of krypton gas. Monoatomic gas.0.405 grams Kr (1 mole Kr/83.80 grams)= 0.004833 moles krypton gas======================Now the ideal gas equation.PV = nRT(1 atm)(X volume) = (0.004833 moles Kr)(0.08206 L*atm/mol*K)(298.15 K)= 0.118 Liters of krypton gas--------------------------------------


What mass does 3.99 moles of Kr have?

To find the mass of 3.99 moles of Kr (krypton), you need to multiply the number of moles by the molar mass of Kr. The molar mass of Kr is approximately 83.80 g/mol. So, the mass of 3.99 moles of Kr would be approximately 334.60 grams.
