What is heavier nitrogen or helium?
Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).
Which has the least number of atoms 5g of hydrogen or 10g of helium?
10g of helium has fewer atoms. This is because the atomic mass of helium is much higher than that of hydrogen, so the same mass of helium contains fewer atoms than the same mass of hydrogen.
What is the mass in grams of 1.5 moles of helium?
The mass of 1,5 moles of helium is 6,003 903 g.
What is the mass of 43.7 L of helium at STP?
The mass of 43,7 L of helium at STP is 7.8 g.
What is the atom if the mass is 2.67x10-24 g?
There is no atom with that mass. Even hydrogen, the lightest element, has an atomic mass of 1.674 x 10 ^ -21 g
What is the mass of helium?
helium = 4 molar mass
How much does atomic mass helium have?
It's just 4.002602 amu
What is the atomic mass of helium if you know that 2.5 mo of helium has a mass of 10 grams?
Atomic mass = weight in gram / moles = 10 / 2.5 = 4 amu
What is the atomic mass average for helium?
Helium is a non metal element. Atomic mass of it is 4.00.
What is the noble has gas with the lowest atomic mass?
Helium with an atomic mass of 4.00260
What is atomic mass for helium?
Helium is a non metal element. Atomic mass of it is 2.
What has more mass hydrogen or helium?
Helium has more mass than hydrogen. Helium is composed of two protons and two neutrons, while hydrogen is a single proton.
What is the relative atomic mass of Helium?
Approximately 4.01
What is heavier nitrogen or helium?
Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).
Which has the least number of atoms 5g of hydrogen or 10g of helium?
10g of helium has fewer atoms. This is because the atomic mass of helium is much higher than that of hydrogen, so the same mass of helium contains fewer atoms than the same mass of hydrogen.
What is the average atomic mass of Helium?
The average atomic mass of helium is approximately 4.0026 atomic mass units (amu). This value is a weighted average of the isotopes of helium, primarily consisting of helium-4 with a small contribution from helium-3.
What element does a low mass star stop at and why?
Helium. A low mass star does not have enough mass to generate the heat needed to fuse helium.
