Answer:
The answer is
<h2>5.50</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 22 g
density = 4 g/mL
The volume is
We have the final answer as
<h3>5.50 mL</h3>
Hope this helps you
Answer:
3441.6 grams.
Explanation:
2 O₃ → 3 O₂
First we <u>convert 71.7 moles of ozone (O₃) into moles of oxygen gas (O₂)</u>, using the <em>stoichiometric coefficients</em> of the reation:
71.7 mol O₃ * = 107.55 mol O₂
Then we <u>convert 107.55 moles of O₂ into grams</u>, using the <em>molar mass of O₂</em>:
107.55 mol * 32 g/mol = 3441.6 g
Answer:
31°C
Explanation:
Using the ratio, we can find the temperature of the gas at 705mm.
725mm : 32°C
705mm : <em>x</em>
[ <em>x</em> is the temperature we have to find ]
Cross multiply the ratios.
725<em>x</em> = 705 × 32
725<em>x</em> = 22560
<em> x</em> = = <u>31°C</u>
