C = Carbon

If you look in a periodic table and see the mass number for carbon. Its estimated around 12.

I believe it's between 1-2 moles.

All you have to do is 13/12 which will give yoy the estimated answer which is around 1.08 mole.

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

The research of astronomy during the time period of 1970 - 1990 is given below:

<u>Date</u>                                                   <u>Event</u>

1. 15 June 1974               Black Brant VC sounding rocket from White Sands.

2. 14 May 1973              Launch of Skylab, the USA's first space station

3. 26 July 1971           Launch of Apollo 15

<h3>What is Astronomy?</h3>

This refers to the branch of science that deals with celestial bodies and their relation to each other.

Hence, from information about astronomy, between the time period 1970 - 1990 as it was on the 26th of December, 1974 that the Soviet space station Salyut-4 was launched.

The event I think had the greatest impact in astronomical history during this time period was the launch of Apollo 16.
