A substance has a volume of 20 mL and a density of 2.5 g/mL. What is its mass?
2 answers:
Answer:
<h2>mass = 50 g</h2>
Explanation:
Density of a substance can be found by using the formula
From the question
Density = 2.5 g/mL
volume = 20 mL
To find the mass substitute the values into the above formula and solve for the mass
That's
Making mass the subject we have
mass = Density × volume
mass = 2.5 × 20
We have the final answer as
<h3>mass = 50 g</h3>
Hope this helps you
Answer:
mass=?,volume=20,density=2.5.
density=mass/volume.
which will be 2.5=mass/20
which is mass=2.5×20=50kg
