Calculate the number of Cl atoms that are in 1.1 x 10^-21 moles of Cl atoms.
Margarita [4]

According to Avogadro's number there are 62.53 atoms of chlorine in 1.1x 10^-21 moles of Cl atoms.

<h3>What is Avogadro's number?</h3>

Avogadro's number is defined as a proportionality factor which relates number of constituent particles with the amount of substance which is present in the sample.

According to the definitions, Avogadro's number depend on determined value of mass of one atom of those elements.It bridges the gap between macroscopic and microscopic world by relating amount of substance with number of particles.

Number of atoms can be calculated using Avogadro's number as follows: mass/molar mass×Avogadro's number or number of moles×Avogadro's number.

ON substitution in above formula number of atoms=1.1×10²¹×6.023×10²³=62.53 atoms

Thus, there are 62.53 chlorine  atoms in 1.1x 10^-21 moles of Cl atoms.

A 150 mL sample of hydrochloric acid (HCl) completely reacted with 60. 0 mL of a 0. 100 M NaOH solution. The equation for the re
SSSSS [86.1K]

Answer:

The balanced chemical reaction is expressed as:

HCl + NaOH ---> NaCl + H2O

We are given the amount and the concentration of the sodium hydroxide reactant. This will be the starting point for the calculations.

0.100 mol NaOH/L solution (0.06 L solution) ( 1 mol HCl / 1 mol NaOH) = 0.006 mol HCl

Molarity = amount in moles / Volume of solution = 0.006 mol HCl/ 0.150 L

Molarity = 0.04 M
