What is the mass of 22.4L of H2 at stp
bazaltina [42]

Answer:

2.02 g H₂

General Formulas and Concepts:

<u>Chemistry - Atomic Structure</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis
  • STP (Standard Conditions for Temperature and Pressure) = 22.4 L per mole at 1 atm, 273 K

Explanation:

<u>Step 1: Define</u>

22.4 L H₂ at STP

<u>Step 2: Identify Conversions</u>

STP - 22.4 L / mol

Molar Mass of H - 1.01 g/mol

Molar Mass of H₂ - 2(1.01) = 2.02 g/mol

<u />

<u>Step 3: Convert</u>

<u />22.4 \ L \ H_2(\frac{1 \ mol \ H_2}{22.4 \ L \ H_2} )(\frac{2.02 \ g \ H_2}{1 \ mol \ H_2} ) = 2.02 g H₂

A. Kids make slime following these basic steps;

1. In a bowl, is 1/4 cup of water is added to 1 oz. of glue. Add coloring if you wish to.

2. 1/4 cup of Borax solution, also known as Sodium Tetraborate is added to the mixture and gradually stirred.

3. The mixture is kneaded with the hands to ensure a smooth consistency.

4. Water remnants are discarded and the slime is stored in a plastic bag and kept in the fridge.

B.

What each ingredient does

Polyvinyl acetate present in the glue acts as a liquid polymer.

Borax binds the liquid polymers together.

Water eases the mixing process

C.

If lesser ingredients are used, the slime will not have its characteristic slimy nature. If excess of the ingredients are used, the slime becomes very sticky.
