K-means is an iterative algorithm where some steps are repeated. What steps are repeated in a complete execution of K-means?

A 3.2-L volume of neon gas (Ne) is at a pressure of 4.7 atm and a temperature of 400 K. The atomic mass of neon is 20.2 g/mol, Avogadro’s number is 6.022×1023 molecules/mol, and the ideal gas constant is R= 8.314 J/(mol·K) = 0.0821 L·atm/(mol·K). The mass of the neon gas is closest to
