1 Na = 23 g/mol
1 mole of Na atom contain an Avogadro Number of atoms .
23g of Na Na atom contain 6.02 * 10²³ atoms.
175 g of Na will contain: 175 * <span>6.02 * 10²³ / 23
</span>
≈ 4.580 * 10²⁴ atoms of Na.
From the addition of 1 equivalent of HBr to 1,3-butadiene, 3-bromo-1-butene is obtained as a product.
What is moles?
Moles are defined as the smallest base unit that is equivalent to
units.
Moles are chemical entities, which are used to measure the mass or molecular mass of the compound, molecule, or atom. The moles are, for example can be explained as equal to the mass of the atom. For example, there is one mole in 12 grams of carboncarbon.
Thus the kinetic product formed is 3-bromo-1-butene.

Answer:
Molecular mass, 
Explanation:
Given that,
Mass of gas, m = 0.46 g
Volume of the container, V = 515 cm^3
Pressure, P = 153 kPa
Temperature, T = 322 K
We need to find the molecular mass of this gas. We know that,
PV =nRT
n = no of moles

No of moles = mass/molecular mass
Let molecular mass is M

So, the molecular mass of this gas is 
Amplitude is 5m and wavelength is 100m
!let me know if I'm wrong bc im a little rusty!
8.40 ml. I think that is right.
