What is the molar mass of Kl(potassium iodide)?
The molar mass of potassium iodide (KI) can be calculated by adding the atomic masses of potassium (K) and iodine (I). The atomic mass of potassium is approximately 39.10 g/mol, and that of iodine is about 126.90 g/mol. Therefore, the molar mass of KI is approximately 166.00 g/mol.
What mass of KI is present in 276 mL of a 0.50 M solution?
To calculate the mass of KI in the solution, first calculate the number of moles of KI present using the formula moles = Molarity x Volume (in liters). Then, use the molar mass of KI (potassium iodide) to convert moles to grams. The molar mass of KI is 166 g/mol.
Calculate the mass of ki in grams required to prepare 5.00 102 ml of a 2.80 m solution?
To calculate the mass of KI needed for a 2.80 m solution, we first need to know the molality (m) and the volume of the solution. The molality is defined as moles of solute per kilogram of solvent. For a 2.80 m solution, we have 2.80 moles of KI per kg of solvent. Given the volume of 5.00 x 10² mL (or 0.500 kg of water, assuming the density of water is 1 g/mL), we can use the formula: Mass of KI = moles of KI × molar mass of KI. Calculating, we find that 2.80 moles of KI correspond to about 2.80 × 166 g/mol (molar mass of KI) = 464.8 g of KI. Thus, you need approximately 464.8 grams of KI.
What is the molarity of 820mL of Kl solution that contains 36.52g of Kl?
To find the molarity (M) of the KI solution, first convert grams of KI to moles using its molar mass (KI's molar mass is approximately 166 g/mol). Moles of KI = 36.52 g / 166 g/mol ≈ 0.220 moles. Then, convert the volume from mL to liters: 820 mL = 0.820 L. Finally, calculate the molarity: M = moles/volume = 0.220 moles / 0.820 L ≈ 0.268 M. Thus, the molarity of the KI solution is approximately 0.268 M.

What mass of KI is present in 276 mL of a 0.50 M solution?
To calculate the mass of KI in the solution, first calculate the number of moles of KI present using the formula moles = Molarity x Volume (in liters). Then, use the molar mass of KI (potassium iodide) to convert moles to grams. The molar mass of KI is 166 g/mol.
What is the percent composition of potassium in potassium iodide Kl?
The percent composition of potassium in potassium iodide (KI) is 58.5%. This is calculated by dividing the atomic mass of potassium by the molar mass of KI and multiplying by 100.
How many grams of KI are required to prepare 500ml of 0.04 M KI?
To calculate the grams of KI required, use the formula: grams = molarity (M) × volume (L) × molar mass (g/mol). The molarity is 0.04 M and the volume is 0.5 L (500 ml). The molar mass of KI is approximately 166 g/mol. Therefore, grams of KI required = 0.04 M × 0.5 L × 166 g/mol = 3.32 grams.

Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
What is the molar mass of sulfur?
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
What is the molarity of 820mL of Kl solution that contains 36.52g of Kl?
To find the molarity (M) of the KI solution, first convert grams of KI to moles using its molar mass (KI's molar mass is approximately 166 g/mol). Moles of KI = 36.52 g / 166 g/mol ≈ 0.220 moles. Then, convert the volume from mL to liters: 820 mL = 0.820 L. Finally, calculate the molarity: M = moles/volume = 0.220 moles / 0.820 L ≈ 0.268 M. Thus, the molarity of the KI solution is approximately 0.268 M.
