What is the mass of sodium (na) in 50 grams of table salt (nacl)? show your work.

The amount of sodium in this sample = 32.4 grams

Explanation:

Mass of Sodium = 23 g/mol

Mass of Chlorine = 35.5 g/mol

Mass of NaCl = 35.5 g/mol

Fraction of Na in NaCl =

                                      =0.648

We are given a sample of 50 grams of sodium chloride.

The amount of sodium in this sample =

The amount of sodium in this sample =

The amount of sodium in this sample = 32.4 grams

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

its first and third is your answer i did the qustion the fourth isnt right
