Given that sodium chloride is 39.0% sodium by mass, how many grams of sodium chloride are needed to have 950.mg of na present?

2.4358 grams of sodium chloride have 950.mg of sodium.

Explanation:

Percentage of sodium in sodium chloride = 39.0 \%

Given mass of the sodium = 950 mg = 0.950 g

Let the mass of sodium chloride be M

Percentage of sodium:

M = 2.4358 g

2.4358 grams of sodium chloride have 950.mg of sodium.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
