How many moles are in 74 g of KCI?

How many moles are in KCl?

One mol of KCl is equal to 74.6 grams (from the periodic chart, the gram-atomic mass of potassium is 39.0 and that of chlorine is 35.5. Add together for the gram-molecular mass of 74.6). If you took 74.6 grams of KCl and diluted this to one liter with water, you would have a 1.00 M KCl solution.

How many grams are in 1 mole of KBR?

Explanation: Now the molar mass of potassium bromide is 119.0⋅g⋅mol−1 .

How many grams are in 1 mole of CCl4?

1 mole is equal to 1 moles CCl4, or 153.8227 grams.

How many moles of KCl are produced from 25 g of K?

2.05 moles of Potassium Chlorate will produce 2.05 moles of Potassium Chloride.

What is the formula for moles to grams?

Moles to grams example problem

Solution: Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KClO3 is 122.548 g/mol. Multiply the given number of moles (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.

How do I calculate moles?

How to find moles?

  1. Measure the weight of your substance.
  2. Use a periodic table to find its atomic or molecular mass.
  3. Divide the weight by the atomic or molecular mass.
  4. Check your results with Omni Calculator.

How many grams are in 0.125 moles of KCl?

Thus, add to get the molar mass for KCl , which is 73.551g/mol .

How many grams are in 2 moles of NaBr?

1 Expert Answer

We use total molar mass of NaBr to convert from moles of NaBr into grams of NaBr. 22.99+79.90= 102.89 g/mol NaBr. So, there is 226.36 grams of NaBr in 2.20 moles of NaBr.

How many moles is CuSO4?

Number of moles in 24.9 g of CuSO4. 5H2O: number of moles = mass / molar mass = 24.9 / 249.72 = 0.100 mol.
