How many grams of sodium Phosphate is needed to prepare 5.0 L of a 2.6M solution ?
Diano4ka-milaya [45]

Molarity is the ratio of the moles and the volume. The mass of 2.6 M sodium phosphate solution is 2131.22 gms.

<h3>What is mass?</h3>

Mass is the product of the moles and the molar mass of the substance. It is given as,

Mass = Moles × Molar mass

The moles from molar concentration is used to calculate mass as:

Mass = Molarity × volume × molar mass

= 2.6 × 5.0 × 163.94

= 2131.22 gms

Therefore, 2131.22 gms is the mass of sodium phosphate.
