Final answer:
To determine the number of grams in 0.0964 mol of potassium, you multiply the molar mass of potassium (39.10 g/mol) by the number of moles, resulting in approximately 3.77 grams.
Step-by-step explanation:
To find out how many grams are in 0.0964 mol of potassium, we need to use the concept of molar mass from chemistry. The molar mass of an element is the weight of one mole of that element. For potassium (K), the molar mass is approximately 39.10 g/mol. We can calculate the mass in grams by multiplying the number of moles by the molar mass of potassium.
The calculation is as follows:
Mass = number of moles × molar mass of K
Therefore,
Mass = 0.0964 mol × 39.10 g/mol
Mass = 3.76884 grams (rounded to 3.77 grams when following significant figure rules)
