Answer:
0.120M is the concentration of the solution
Explanation:
<em>Assuming the mass of sodium nitrate dissolved was 2.552g</em>
<em />
Molar concentration is an unit of concentration widely used in chemsitry defined as the moles of solute (In this case NaNO3) in 1L of solution.
To find this question we must find the moles of NaNO3 in 2.552g. With this mass and the volume (250mL = 0.250L) we can find molar concentration as follows:
<em>Moles NaNO3 -Molar mass: 84.99g/mol-</em>
2.552g * (1mol / 84.99g) = 0.0300 moles NaNO3
<em>Molar concentration:</em>
0.0300 moles NaNO3 / 0.250L =
<h3>0.120M is the concentration of the solution</h3>

Explanation:
The term conservation of mass means that mass in any system can neither be created nor destroyed but can be transformed from one state to another.
<h3>What is the law of mass of conservation?</h3>
The law of conservation states that the mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another.
This means that when an element is involved in a chemical reaction, it's mass remains the same at the end of that reaction.
