How many potassium atoms are there in a sample of K2Cr2O7 having a mass of 24.43 g?
The number of potassium atoms is 2,04.10e21.
How many atoms of potassium make up 3 moles?
Firstly, you'll need to convert the grams into number of mols. Since no. of mol = mass/molecular weight 3.55/39.1 = 0.09079 mol because 1 mol of potassium consists of 6.02x10^23 atoms; 0.09079 mol of potassium will consist of 0.09079x(6.02x10^23)=5.466x10^22 atoms of potassium.
How do you calculate a mole of an atoms weight in grams?
you take the atomic mass of the atom (or molecule) and you have the mass in grams
How can you fine the mass of mole of atoms of atoms of an element in grams?
Simple: the atomic weight expressed in grams. Example for dysprosium - 162,500 grams.
What is the mass in grams of 6.022 x 1023 N atoms of mass 14.01 amu?
The molar mass of any element is its atomic weight (amu) in grams, and 1 mol of any element is 6.022 x 1023 atoms. Therefore, the mass in grams of 6.022 x 1023 atoms of N = 14.01g N.
How many grams do 4.4 x 1022 atoms of potassium weigh. answer in units of grams?
The mass is 2.86 grams but the weight will be 0.028 Newtons.
What is the mass of potassium if a potassium sample contains 5 times the number of atoms as in 9.85 grams of gold?
The gram atomic mass of gold is 196.967 and that of potassium is 39.0983. Therefore, equal numbers of atoms of potassium are supplied by 39.0983/196.967 the mass of potassium compared with gold. 5 X 9.85 = 49.25. This contains the same number of gold atoms as 49.25(39.0983/196.967) or 9.78 grams of potassium contains of potassium atoms, to the justified number of significant digits (limited by the number "9.85", assuming that "5" is intended to be exact.)
How much mass is in potassium?
Every atom of potassium has a mass of 39 amu. Each mole of potassium has a mass of 39 grams.
Calculate the approximate mass of KHC8H404?
The separate components of this compound, potassium hydrogen phthalate are one potassium, five hydrogen, eight carbon and four oxygen atoms. The total molar mass is then 204.221 grams per mole.
How many potassium atoms are there in a sample of K2Cr2O7 having a mass of 24.43 g?
The number of potassium atoms is 2,04.10e21.

What is the mass in grams of 0.5 moles of potassium?
The atomic mass of potassium, K is 39.1. This means that 1 mole of potassium has a mass of 39.1g. Mass of 0.5mol of K = 0.5 x 39.1 = 19.6g
What is the mass of 5 moles of Potassium Sulphate?
871 grams
What is the mass of 0.41 mol of the element potassium?
The gram-atomic mass of potassium is 39.098. This number multiplied by 0.41 = 16 grams.
How to convert grams to atoms?
To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.
Where is most of potassium atoms mass located?
The nucleus - protons and neutrons. This applies to all atoms.
How do you calculate a mole of an atoms weight in grams?
you take the atomic mass of the atom (or molecule) and you have the mass in grams
