Explanation:

Step 1: Define

2.1 × 10²⁶ atoms Cs

Step 2: Identify Conversions

Avogadro's Number

Molar Mass of Cs - 132.91 g/mol

Step 3: Convert

Step 4: Check

Follow sig fig rules and round. We are given 2 sig figs.

46348.6 g Cs ≈ 46000 g Cs

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

answer; i believe that the correct answer is (a) potassium(k)
