How many molecules are in 39 moles of neon?
1 mole = 20.18 g of Neon = 6.023 x 1023 atoms of neon (A neon molecule has only one atom) So, 39 moles = 39 x 6.023 x 1023 atoms = 234.897 x 1023 atoms of neon
How many moles of sugar are in 1 soda can of 39 g?
To find the number of moles of sugar in a soda can containing 39 grams of sugar, you need to know the molar mass of sugar (sucrose, C12H22O11), which is approximately 342 g/mol. Using the formula: moles = mass (g) / molar mass (g/mol), you can calculate the moles: moles = 39 g / 342 g/mol ≈ 0.114 moles. Therefore, there are about 0.114 moles of sugar in a 39 g serving of soda.
How many moles are in 48g of KCl?
KCl has a molar mass of 39+35.5=74.5g/mol, and 48/74.5=0.64mol.
What is the atomic number of potassium and sodium?
Potassium is a non metal element. Atomic number of it is 39.
How many neutrons are in an atom of this isotope if the atomic number of yttrium is 39 and the atomic mass of the isotope is 89?
The number of neutrons in an atom can be calculated by subtracting the atomic number (protons) from the atomic mass. In this case, for the isotope of yttrium with an atomic number of 39 and an atomic mass of 89, the number of neutrons is 50 (89 - 39 = 50).
How many molecules are in 39 moles of neon?
1 mole = 20.18 g of Neon = 6.023 x 1023 atoms of neon (A neon molecule has only one atom) So, 39 moles = 39 x 6.023 x 1023 atoms = 234.897 x 1023 atoms of neon
Find moles of Au in 2.88X1023 atoms of Au?
1 mol = 6.02 x 10^23 2.88 x 1023 atoms = 2946.24 atoms = (2946.24) / (6.023 x 10^23) moles = 4.89 x 10^-21moles Or if you meant=> 2.88 x 10^23 atoms = (2.88/6.02) moles = 0.478 moles (3 s.f)

How much sodium in kosher salt?
Table salt and kosher salt are both 39% sodium by weight.
How many atoms are there in 39 g of potassium?
The atomic mass of potassium is 39 ,therefore the number of mole is 39 /39,which is 1then multiple by Avogadro number you get 6.022*10^24
How many atoms of krypton are in 2.50 moles of Kr gas?
The mass in grams of KBr contained in 2.50 moles of the compound is 2.5 times the sum of the gram atomic masses of hydrogen and bromine, or 2.50(1.008 + 79.904) or 202 grams, to the justified number of significant digits.
How many liters of oxygen is required for the combustion of 39 grams of liquid benzene?
To find the amount of oxygen required for the combustion of liquid benzene, you would need to balance the combustion reaction equation for benzene. Calculate the moles of benzene from the given mass, then use the stoichiometry of the balanced equation to determine the moles of oxygen required. Finally, convert the moles of oxygen to liters using the ideal gas law.
Why is 1.5 moles equivalent to 39 grams of LiF?
Li: atomic mass 6.941F: atomic mass 18.998Lithium fluoride is made up of these two elements. Its balanced formula is LiF (Li+1F-1). Adding both its atomic masses equals 25.939. Therefore one mole of LiF is equal to 25.939 grams. So, 1.5 moles of LiF is equal to 38.90 grams.
