Answer:
mass = 29.25 g
Step-by-step explanation:
The denisty of a substance can be found by using the formula
![Density = (mass)/(volume)](https://img.qammunity.org/2021/formulas/chemistry/high-school/el4r75hf1brsg5k4a45db8ptpkl6z9kys6.png)
Making mass the subject we have
mass = Density × volume
From the question
Density = 2.34 g/mL
volume = 12.50 mL
Substitute the values into the above formula and solve for the mass
That's
mass = 2.34 × 12.50
We have the final answer as
mass = 29.25 g
Hope this helps you
