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 />
= 2.02 g H₂
Answer:their particles are more spread out than others
Explanation:
Answer:
1600cm3
Explanation:
From the question given, we obtained the following:
Density = 2.70g/cm3
Mass = 4.32kg :we need to convert the mass to grams
Mass = 4.32kg = 4.32 x 1000 = 4320g
Volume =?
Recall : Density = Mass /volume
Volume = Mass /Density
Volume = 4320/2.70
Volume = 1600cm3
