Final answer:
To calculate the mass of sodium in 6.00 grams of sodium chloride, you can use the percent composition of sodium in sodium chloride. The result is approximately 2.36 grams.
Explanation:
To determine the mass of sodium in 6.00g of sodium chloride (NaCl), we should understand that the sodium chloride molecule is made up of one atom of sodium (Na) and one atom of Chloride (Cl). The atomic mass of sodium is approximately 23 g/mol and the atomic mass of chloride is approximately 35.5 g/mol. The entire sodium chloride molecule therefore has a molar mass of about 58.5 g/mol. We are only interested in the sodium portion, which contributes to about 39.32 percent of the total mass.
The mass of sodium in 6.00 g of NaCl can be calculated as follows:
mass of sodium = (mass of the sample) * (percent composition of sodium)
mass of sodium = 6.00g * (23 g/mol) / (58.5 g/mol) = 2.36g
So, if you consumed 6.00g of sodium chloride in a day, you have ingested approximately 2.36 g of sodium.

Answer: 2.36 grams
Explanation: One molecule of NaCl has an atomic mass of 58.4 amu. That consists of one atom each of sodium (23 amu) and chlorine (35.4 amu).
Na 23 (23/58.4) = 0.3934
Cl 35.4 (35.4/58.4) = 0.6066
58.4 amu
For Na: (6 grams)*(0.3934) = 2.36 grams
