Answer:
The volume of the neon gas is 17.07 L.
Explanation:
The ideal gas equation describes the relationship among the four variables P, V, T, and n. An ideal gas<u> is a hypothetical gas whose pressure-volume-temperature behavior can be completely accounted for by the ideal gas equation</u>.
In order to calculate the volume, first we need to convert the grams of neon to moles:
28.18 g Ne ------ 1 mol Ne
5.0 g Ne---------- <u>x= 0.25 mol Ne</u>
Now, using the ideal gas equation we calculate the volume:
V= 17.07 L

Answer:
liquid vibrate, move about, and slide past each other. solid vibrate (jiggle) but generally do not move from place to place.
Explanation:
Answer:
the mas is .291 g
Explanation:
the mass of a object does not change. so when added the substance the beaker. you had the mass of both objects together. you know the mass of the beaker and you know the mass of both. since mass does not change. the beakers mass is still 74.605g. the mass of both objects is 74.896. all you have to do is subtract the mass of the beaker from the total mass. 74.896 - 74.605 equals .291g. so the mass of the unknown substance Is .291g
