Answer:
The answer is
<h2>0.14 g</h2>
Explanation:
To find the mass of a substance given the density and volume we use the formula
<h3>mass = Density × volume</h3>
From the question
Density = 1.122 g/L
volume = 125 mL
We must convert the volume from mL to L
1000 mL = 1 L
125 mL = 0.125 L
volume = 0.125 L
Substitute the values into the above formula and solve for the mass
That's
mass = 1.122 × 0.125 = 0.14025
We have the final answer as
<h3>0.14 g</h3>
