Under what sets of conditions will a 0.50 mole sample of helium occupy a volume of 11.2 liters?
At STP, 1 mole of a gas will occupy 22.4 liters; or 0.5 mole will occupy 11.2 liters.
A sample of Helium gas weighs 4.00 g (grams) and occupies 22.4 L (liters) when it is at 0 degree Celsius and 760 mm Hg pressure. What is the mass of the sample in grams?
The mass of the helium gas sample is already given as 4.00 grams. This value represents the weight of the gas under the specified conditions of temperature and pressure. Therefore, the mass of the sample is 4.00 grams.
What is the total number of atoms contained in a 1.00 mole sample of helium?
The total number of atoms contained in a 1,00 mole sample of helium is 6,022 140 857.10e23.
If there was 7.48 gallons in a cubic foot how much volume would 1lb of helium gas occupy?
That depends on the pressure inside the container. You can cram 1 lb of helium into any container, as small as you want. On the other hand, it'll always spread out and fill any container you put it in, no matter how large. So if you want to know how much volume a sample of helium will fill, you have to specify the pressure. By the way ... the temperature also affects the pressure of a gas, so you have to specify the temperature too.
Why helium is used for PECVD?
it is used to carry TEOS to the sample

A 1-gram sample of which substance in a sealed 1-liter container will occupy the container completely and uniformly?
A 1-gram sample of a noble gas, such as helium, in a sealed 1-liter container will occupy the container completely and uniformly. The noble gas atoms are non-reactive and have low mass, allowing them to distribute evenly across the container due to their high kinetic energy and lack of attractive intermolecular forces.
What is the purpose of the helium gas in the GC machine?
The purpose of the helium gas in the GC (gas chromatography) machine is to act as the carrier gas. The helium gas carries the sample through the column, allowing for the separation and analysis of the various components in the sample. Helium is commonly used as the carrier gas due to its inertness and low molecular weight, which facilitates efficient sample transport.
How much atoms does helium have?
Atomic Mass of helium is 4.002602
How do you make a pure sample of helium?
A pure sample of helium can be obtained by extracting it from natural gas through a process called fractional distillation. This involves cooling the natural gas to very low temperatures, which causes the various components to condense at different points. By isolating the helium gas at the corresponding temperature, a pure sample can be obtained.
The volume of a sample of seawater is 932 ml what is its volume in liters?
932 mL = 0.932 LTo convert from mL to L, divide by 1000.
Does one ml have the same density of 15 liters?
Any sample of the same substance has the same density,no matter how large or small the sample is.
What is the amount of space that a sample of matter occupies?
The amount of space that a sample of matter occupies is called its volume. This can be measured in units such as cubic meters, liters, or cubic centimeters depending on the scale of the sample.
