Answer:
Hydrogen
Explanation:
Hydrogen has only 1 proton and has an atomic mass of 1. It does not have neutrons. Helium and above have higher mass than Hydrogen.
Answer:
The correct answer to the following question will be "NaCl".
Explanation:
- A solute is being known as the soluble material within a liquid or a solution. The solvent is available in larger quantities than those of the solute among fluid.
- Concentration seems to be a calculation including its quantity of solvent contained in such a liquid solution, regard to something like the solvent volume.
So that NaCl is the right answer.
835 g Ar to liters of Argon gas is calculated as follows
find the moles of Ar = mass/molar mass
= 835g /39.95 g/mol = 20.9 moles
At STP 1mole of ideal gas = 22.4 L, what about 20.9 moles
= 20.9 moles/1mole x 22.4 L =468.16 L of Argon
Answer : The molarity of the solution is, 1.1 M LiCl
Explanation : Given,
Mass of
= 32 g
Volume of solution = 655 mL
Molar mass of
= 42.4 g/mole
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :

Now put all the given values in this formula, we get:

Therefore, the molarity of the solution is, 1.1 M LiCl
What is the answer to this question
