What is the volume and temperature of the helium gas?

CJ questioned:

If 18.75 mol of helium gas is at 10.0 top C and a gauge pressure of 0.350 atm, (a) calculate the number of the helium gas below these conditions. (b) Calculate the like if the gas is compressed to precisely half the number at a gauge pressure of 1.00 atm.

What will happen to the gas pressure after the stopcock is opened?

XXMB21BXX questioned:

Two flasks of copy size are collectively by a narrow tube that is clogged in the midpoint with a stopcock. One flask has no gas particles; the additional flask contains 0.1 mol of hydrogen gas at a pressure of 2.0 atm.

What temperature does the gas need to be at to fill the balloon?

Vic questioned:

You have a gas try out that is now at an unknown number. You need the gas to enlarge to fill a balloon that has a room of 50 L. You know its pressure is 1.05 atm and that you have 1.90 mol of the gas. What like does the gas need to be at to fill the balloon?

How to find the volume of oxygen gas collected in water decomposed?

Smilely questioned:

When fill up is subjected to an gripping current, it decomposes to hydrogen and oxygen gas. If 1.00g of fill up is moldy at 1.00 atm and 25 top Celsius, what number of oxygen gas is collected?
