Calculate the mass in grams of 2.60 mol of potassium chloride (kcl). the answer isn't 193.8338 if you give that i will report you. answer correctly it is hurting my brain.

Given:
2.60 mol of potassium chloride (KCl)

Three steps to converting moles of a substance to grams:

1) Determine how many moles are given in the problem.
2) Calculate the molar mass of the substance.
3) Multiply step one by step two.

1) 2.60 mol 
2) These are their atomic masses:
Potassium, K, has 39.0983 g/mol
Chlorine, Cl, has 35.453 g/mol
Total molar mass of potassium chloride is: 39.0983 g/mol + 35.453 g/mol = 74.5513 g/mol
3) 2.60 mol * 74.5513 g/mo =  193.83338 grams

193.83338 grams rounded to 2 significant places 193.83 grams.
