The mass of sodium in 5.85 g of NaCl is 2.3 g.
NaCl is the chemical formula for sodium chloride, commonly known as table salt. It is composed of sodium (Na) and chloride (Cl) ions in a 1:1 ratio. In order to find the mass of sodium in 5.85 g of NaCl, we need to calculate the molar mass of NaCl and then determine the mass ratio of sodium to NaCl.
Step 1: Calculate the molar mass of NaCl.
The molar mass of an element or compound is the mass of one mole of that substance. In the case of NaCl, we need to determine the molar mass of sodium (Na) and chlorine (Cl) and then add them together.
The atomic mass of sodium (Na) is 22.99 g/mol, and the atomic mass of chlorine (Cl) is 35.45 g/mol. Since NaCl has one sodium atom and one chlorine atom, the molar mass of NaCl is:
Molar mass of NaCl = (1 * atomic mass of Na) + (1 * atomic mass of Cl)
= (1 * 22.99 g/mol) + (1 * 35.45 g/mol)
= 22.99 g/mol + 35.45 g/mol
= 58.44 g/mol
Therefore, the molar mass of NaCl is 58.44 g/mol.
Step 2: Determine the mass ratio of sodium to NaCl.
Now that we know the molar mass of NaCl, we can determine the mass ratio of sodium to NaCl using the given mass of NaCl (5.85 g).
Mass ratio of sodium to NaCl = (mass of sodium / mass of NaCl)
Since we want to find the mass of sodium, let's rewrite the equation as:
mass of sodium = mass ratio of sodium to NaCl * mass of NaCl
mass ratio of sodium to NaCl = (molar mass of sodium / molar mass of NaCl)
mass ratio of sodium to NaCl = (22.99 g/mol / 58.44 g/mol)
= 0.393
mass of sodium = 0.393 * 5.85 g
= 2.3 g
Therefore, the mass of sodium in 5.85 g of NaCl is 2.3 g.

= 58.44 g/mol
Therefore, the molar mass of NaCl is 58.44 g/mol.
Step 2: Determine the mass ratio of sodium to NaCl.
Now that we know the molar mass of NaCl, we can determine the mass ratio of sodium to NaCl using the given mass of NaCl (5.85 g).
Mass ratio of sodium to NaCl = (mass of sodium / mass of NaCl)
Since we want to find the mass of sodium, let's rewrite the equation as:
mass of sodium = mass ratio of sodium to NaCl * mass of NaCl
mass ratio of sodium to NaCl = (molar mass of sodium / molar mass of NaCl)
mass ratio of sodium to NaCl = (22.99 g/mol / 58.44 g/mol)
= 0.393
mass of sodium = 0.393 * 5.85 g
= 2.3 g
Therefore, the mass of sodium in 5.85 g of NaCl is 2.3 g.
