What is the mass in grams of 2x1012 atoms of potassium?
What is the mass, in grams, of 2 × 1012 atoms of potassium?
How many molecules are present in 691 grams of potassium carbonate?
30.115*10^23 molecules
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 many atoms are present in 5 grams of AuCl3?
For this problem, the atomic mass is required. Take the mass in grams and divide it by the atomic mass. Then multiply it by Avogadro's constant, 6.02 × 1023. AuCl3= 303.5 grams5.00 grams AuCl3 / (303.5 grams) × (6.02 × 1023 atoms) = 9.92 × 1021 atoms
How many atoms are present in 6.81g of copper?
6.81 grams copper (1 mole Cu/63.55 grams)(6.022 X 1023/1 mole Cu) = 6.45 X 1022 atoms of copper ----------------------------------------
What is the mass in grams of 2x1012 atoms of potassium?
What is the mass, in grams, of 2 × 1012 atoms of potassium?
How many grams are in 1.34 x 1034 potassium atoms?

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 many molecules are present in 691 grams of potassium carbonate?
30.115*10^23 molecules

How many hydrogen atoms are present in 3.65 grams of water?
3.65 grams of water is equal to .203 moles of H2O. This means there is also .203 moles of H2 present, or .408 grams.
He formula for potassium dichromate is KËÃCrËÃOËÈ How many grams of oxygen will be in 2 moles of potassium dichromate?
224 grams of Oxygen will be in 2 moles of Potassium dichromate.
How many atoms are in 3.50 moles of calcium?
There are 6.022 × 1023 atoms of potassium in every mole of potassium. Since one mole of KOH contains one mole of K, the answer is 6.022×1023 atoms of K. Therefore, 3.5 moles * 6.022E23 atoms/1 mole= 2.107E24
