To find the number of moles of platinum in 10g, divide the mass by the molar mass of platinum. The molar mass of platinum is approximately 195.08 g/mol. Therefore, there are 0.051 moles of platinum in 10g.
Since molecules of potassium contain only single potassium atoms, molecules of iodine contain two atoms, and moles of potassium iodide contain one atom of each element, 2.5 moles of iodine are needed to react completely with 5 moles of potassium.
Iodine has a molar mass of 129.9g So one mol of Iodine is 129.9g. Therefore 10 moles of iodine would be 1299g.
The element with the largest number of moles would be Neon (Ne) since all substances contain the same mass (10g), and Neon has the lowest molar mass among those elements.
To determine the number of atoms in 10g of Fe, you first need to calculate the number of moles of Fe using its molar mass (55.85 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in those moles of Fe. Finally, multiply the number of moles by Avogadro's number to get the total number of atoms in 10g of Fe.
222,6 grams of iodine is equivalent to 1,754 moles.
To find the number of moles of platinum in 10g, divide the mass by the molar mass of platinum. The molar mass of platinum is approximately 195.08 g/mol. Therefore, there are 0.051 moles of platinum in 10g.
380.7 grams of iodineis equivalent to 3 moles.
There is one mole of iodine in one mole. There are 126.90447grams of iodine in one mole. There are also 6.022x1023 atoms in one mole.
2,196.10-12 pmol of Na3PO4. (p is pico)
Since molecules of potassium contain only single potassium atoms, molecules of iodine contain two atoms, and moles of potassium iodide contain one atom of each element, 2.5 moles of iodine are needed to react completely with 5 moles of potassium.
mol = mass/Mr rearrange mol x Mr = mass 2 x 126.9g = 253.8g
10g Al(OH)3 is 0.12821 moles. The moles of hydroxide is thus, 0.38462 moles. If you have 1.5 moles per litre HCl and they react 1:1, you need 256.4ml
You cannot produce any Iodine from chlorine, because chlorine (Cl2, gas) is an element, hence it does not contain any Iodine (I2, solid with purple vapor). However when 8.00 moles Cl2 react with excess (>16) moles potassium Iodide (KI) then also 8.00 moles of Iodine are produced, not FROM but BY MEANS OF chlorine. Cl2 + 2KI --> 2 KCl + I2
Iodine has a molar mass of 129.9g So one mol of Iodine is 129.9g. Therefore 10 moles of iodine would be 1299g.
