Question

How many grams of
potassium are in 3.25 moles
of potassium?

Answer 1

127 grams K

Step-by-step explanation:

To find the mass of potassium (K), you need to multiply the given moles by the atomic mass of potassium. The atomic mass exists as a ratio comparing the mass of 1 potassium atom per 1 mole. It is important to arrange this ratio in a way that allows for the cancellation of units. The final answer should have 3 significant figures.

Atomic Mass (K): 39.098 g/mol

3.25 moles K 39.098 grams
----------------------- x ------------------------- = 127 grams K
1 mole

Answer 2

127,06947500000001 grams

Step-by-step explanation:

We will show you here, how to convert 3.25 moles of potassium to grams. First, note that potassium is a chemical element that you can find in the periodic table. The symbol for potassium is K, and the symbol for grams is g. Therefore, 3.25 moles of potassium to grams is the same as 3.25 moles of K to grams, 3.25 moles of potassium to g, and 3.25 moles of K to g.

In addition, the atomic mass of potassium is 39.0983. That means that one mole of potassium weighs 39.0983 grams (39.0983 g/mol).

Based on that information, to convert 3.25 moles of potassium to grams, we multiply 3.25 moles of potassium by 39.0983. Here is the Moles of Potassium to Grams Formula, the math, and the answer to 3.25 moles of potassium converted to grams.

Moles of Potassium × 39.0983 = Grams

3.25 × 39.0983 = 127.069475

3.25 Moles of Potassium = 127.069475 Grams.
