What is the mass in grams of 0.375 mol of the element potassium, k

Mass = 14.7 g

Explanation:

Given data:

Mass in g = ?

Moles of K = 0.375 mol

Solution:

Molar mass of potassium is 39.1 g/mol.

Formula

Number of moles = mass/molar mass

Mass = Number of moles × molar mass

Mass = 0.375 mol × 39.1 g/mol

Mass = 14.7 g
