Answer:
La respuesta es
<h2>158 g</h2>
Explanation:
La masa de una sustancia cuando se le da la densidad y el volumen se puede encontrar usando la fórmula
<h3>masa = Densidad × volumen</h3>
De la pregunta
volumen = 100 mL
densidad = 1.58 g/mL
La masa de sustancia es
masa = 100 × 1.58
Tenemos la respuesta final como
<h3>158 g</h3>

It is 2, I hope this helped
Mass of the <span>solvent (H2O) in kg
D = m / V
1.02 = m / 125
m = 1.02 x 125
m = 127.5 g of H2O
127.5 / 1000 => 0.1275 kg
mass of solute in mg:
1000 x ( 1.86 x 10</span>⁻⁵ ) = 0.0186 mg
<span>
ppm = mass of solute in mg / mass of solvent in kg
ppm = 0.0186 / </span><span>0.1275
</span><span>
= 0.1458 ppm
hope this helps!
