The statement that can be made about the samples is that each balloon contains 1 mole of each gas.
<h3>What is molar volume?</h3>
Molar volume refers to the volume that is occupied by one mole of a gas. According to Avogadro, the volume occupied by one ole of a gas is 22.4-L at STP.
Hence, if 22.4-L at STP is the volume of both the helium and argon filled balloons, then each balloon contains one mole of the gas.

Answer:
Explanation:
a self-contained convective zone in a fluid in which upward motion of warmer fluid in the center is balanced by downward motion of cooler fluid at the periphery.
Answer:
True!
Explanation:
Living things are classified by the characteristics they have in common. All living organisms are classified within the organization based on extremely fundamental, shared characteristics.
It's "C" a sample of dust particles at 0 Pascals
Answer:
1.63ₓ10⁻⁶ g of U
139.03 g of H
0.385 g of O
141.8 g of Pb
Explanation:
In first place, we need to convert the number of atoms to moles, as we know that 1 mol of anything occupies 6.02×10²³ particles
Therefore:
4.12×10¹⁵ atoms of U . 1 mol / 6.02×10²³ atoms = 6.84×10⁻⁹ moles of U
8.37×10²⁵ atoms of H . 1 mol /6.02×10²³ atoms = 139.03 moles of H
1.45×10²² atoms of O . 1 mol /6.02×10²³ atoms = 0.0241 moles of O
4.12×10²³ atoms of Pb . 1 mol /6.02×10²³ atoms = 0.684 moles of Pb
Moles . Molar mass = Mass (g)
6.84×10⁻⁹ moles of U . 238.03 g/mol = 1.63ₓ10⁻⁶ g of U
139.03 moles of H . 1 g/mol = 139.03 g of H
0.0241 moles of O . 16 g/mol = 0.385 g of O
0.684 moles of Pb . 207.2 g/mol = 141.8 g of Pb
