What else can I help you with?
What has a greater number of atoms a gram of lead or a gram of uranium?
The lead atom is way heavier than the helium atom. We know this by referring to the Periodic Table of Elements. The atomic mass of lead (Pb) is 207, while that of helium (He) is 4. Therefore, we can estimate that an atom of lead is about 50 times heavier than an atom of helium.
A balloon has a volume of 6.3 liters Calculate the mass of helium that it would take to fill the balloon?
To calculate the mass of helium, you would need to know the density of helium (0.1785 g/L at 0°C and 1 atm). You can use the formula: mass = density x volume. In this case, mass = 0.1785 g/L x 6.3 L = 1.125 g.
What will be the volume of 1g of helium at ntp in liters?
At NTP (standard temperature and pressure), which is 0 degrees Celsius and 1 atm pressure, the volume occupied by 1 gram of helium would be approximately 22.4 liters. This value is based on the ideal gas law and the molar mass of helium.
What is the difference between a carbon atom and a uranium atom?
I won't even waste the time looking up actual numbers.a mole of atoms of helium is about 4 grams, therefor 1 gram of helium is about 0.25 moles of helium atomsa mole of atoms of uranium is about 238 grams, therefor 1 gram of uranium is about 0.0042 moles of uranium atomsA gram of helium contains more atoms than a gram of uranium by about a factor of 60.
Which has greater number of atoms a gram of helium or a gram of neon?
Neon is larger because it has more protons, electrons, and neutrons. Look at the element's Atomic Mass for an idea of its size.

What is relative atomic mass and how it is related with gram?
when atomic mass of an element expressed in gram atom is called gram atom mass . and formula is number of gram atom=given mass (in gram) by atomic mass ( in gram )
How many moles of heLium are contained in 0.255g of helium?
use this formula, n(He)=m(He)/M(molar mass of He) =0.255G/4.OO =0.06375 moles per gram.
