Answer:
[tex] \huge{ \boxed{89.54 \: g}}[/tex]
Explanation:
To find the mass of an object given it's volume and density, we use the formula;
[tex] \bold{density( \rho) = \frac{mass}{volume} \\ }[/tex]
Since the mass is the unknown variable in the question, we make mass the subject and solve.
mass = density × volume
From the question
- density = 1.21 g/ml
- volume = 74 ml
[tex] \text{mass} = 1.21 \times 74 = 89.54[/tex]
We have the final answer as
89.54 g
