2. How many moles are found in 3.2 x 1023 atoms of NaCl?

0.53 mol NaCl

General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

Step 1: Define

3.2 × 10²³ atoms NaCl

Step 2: Identify Conversions

Avogadro's number

Step 3: Convert

= 0.531385 mol NaCl

Step 4: Check

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

0.531385 mol NaCl ≈ 0.53 mol NaCl

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

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
