Answer:
"One mole of any gas has a volume of 24 dm3 or 24,000 cm3 at rtp (room temperature and pressure). This volume is called the molar volume of a gas."
Explanation:
Divide the mass of neon.
Answer: 233 L of 
will be produced from 150 grams of 
Explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
2 moles of produce = 8 moles of
Thus 2.59 moles of will produce=
of
Volume of 
Thus 233 L of will be produced from 150 grams of
This example is an controversial matter because melting an candle is considered as both physical change and chemical change because no new substances were made by melting an candle. The final answer is C.
Mg(OH)2 + 2 HCl → MgCl2 + 2 H2O
(0.0500 L) x (0.500 mol/L HCl) x (1 mol Mg(OH)2 / 2 mol HCl) x (58.3197 g Mg(OH)2/mol) = 0.729 g = 729 mg Mg(OH)2
<span>(729 mg Mg(OH)2) x (5.00 mL / 400 mg) = 9.11 mL milk of magnesia</span>
<span>The average atomic mass of an element is the mass you see on a periodic table for that element. It is a weighted average of all the isotopes for that element based on the percentage of how much of an element is a specific isotope and the mass of each isotope. If an element has an abundance of isotopes, the isotopes with the highest and lowest masses may be more significantly different than the average atomic mass for elements with fewer isotopes.</span>
