Answer:
Matter always takes space (or has volume).
Answer:
Any of the six chemical elements that markup group1
of the periodic table.
Explanation:
Answer:
4.52 mol
Explanation:
We do grams/Molar Mass to find the number of moles. The grams are given but the molar mass, you have to add all masses of the elements up by refering to a periodic table, and you should get that the compound has a mass of 158.168. Do 715.11 dived by that and you get the answer above.
Answer: The original volume in liters was 0.0707L
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
![\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BP_1V_1%7D%7BT_1%7D%3D%5Cfrac%7BP_2V_2%7D%7BT_2%7D)
where,
= initial pressure of gas = 0.85 atm
= final pressure of gas = 456 mm Hg = 0.60 atm (760mmHg=1atm)
= initial volume of gas = ?
= final volume of gas = 94.0 ml
= initial temperature of gas = ![66^oC=273+66=339K](https://tex.z-dn.net/?f=66%5EoC%3D273%2B66%3D339K)
= final temperature of gas =
![(32^0F=273K)](https://tex.z-dn.net/?f=%2832%5E0F%3D273K%29)
Now put all the given values in the above equation, we get:
![\frac{0.85\times V_1}{339}=\frac{0.60\times 94.0}{318}](https://tex.z-dn.net/?f=%5Cfrac%7B0.85%5Ctimes%20V_1%7D%7B339%7D%3D%5Cfrac%7B0.60%5Ctimes%2094.0%7D%7B318%7D)
(1L=1000ml)
Thus the original volume in liters was 0.0707L
