<span>23.8 g/mol Since the definition of molar mass is mass per mole, just divide the mass of the sample by the number of moles you have. So 0.250 g / 1.05x10^-2 mol = 23.8095 g/mol Since our input data only has 3 significant figures, you need to round the result to 3 significant figures. 23.8095 g/mol rounds to 23.8 g/mol</span>

How reactive is an atom of Sodium(Na) and why?
s344n2d4d5 [400]
3rd one:
it is very reactive because it does not have a full Valence shell.

this is because it's in group 1 so it has one electron in its outer shell, and it wants to have a full outer shell ( which it can gain by losing the electron in a reaction).

Hope this helps :)

Calculate the frequency of radiation with a wavelength of 1.08 x 10^-6 m. simple explanation please​
pishuonlain [190]
C = vf
c stands for the speed of waves (which is a constant that is 3 x 10^8)
v stands for the wavelength (which is given)
f stands for frequency (what we are solving for)
3 x 10^8 = (1.08 x 10^-6)f
Divide both sides by the given wavelength
f = 2.78 * 10^14 seconds

How do you classify a metal
Alenkinab [10]

Answer:

They are solid (with the exception of mercury, Hg, a liquid).

They are shiny, good conductors of electricity and heat.

They are ductile (they can be drawn into thin wires).

They are malleable (they can be easily hammered into very thin sheets).

If this satisfies you please consider giving me brainliest :)
