Chemical formula for potassium iodide is KI. Its formula mass is 39.1+127.0=166.1
Amount of KI in 100.0g sample = 100.0/166.1 = 0.602mol
Magnesium iodide is MgI2 so in 1 formula unit there are 3 atoms.
0.359569 mols
About 1.063 moles.
The number of moles of carbon in 11,5 g of ibuprofen is 0,725.
There are 10 moles present in 585 g of sodium chloride.
NaHCO3 ----> H2O Mass 2.10g 0.045g RAM 84 g/moles 18 g/moles number of moles 0.025moles 0.025moles
The answer is 0,1014 moles of sodium.
molarity = no. of moles of solute/liter of solution no. of moles of I2 = mass in grams/molar mass = 4.65/253.81 = 0.01832 mol M = 0.01832 mol/0.235 L = 0.0780 mol/L
In the English language hydrobromic acid is the solution of HBr in water; the name of the acid HBr is hydrogen bromide. 135 g HBr are equivalent to 1,67 moles.
3,80 g Zn have 0,058 moles.
The formula is: number of moles = g Be/9,012.
Moles = weight in g / atomic weight. So moles in 24.7 g of Ar = 24.7 / 39.948 = 0.62 moles
The answer is 0,364 moles.
The answer is 0,4 moles.
The answer is 0,253 moles.
978 g calcium contain 24,4 moles.
14,84 g magnesium are equivalent to 0,61 moles.
