Question

The density of Ed cola is 1.05 g/mL. If the empty can has a mass 35g, then the mass of a can of 300mL of Ed cola is

• A. 300 g
• B. 400 g
• C. 350 g
• D. 325 g

Answer 1

The correct option is C 350 g

Given that density of Ed cola is 1.05 g/mL
i.e. 1mL of Ed cola weighs 1.05 g mass.
Let mass of 300mL of Ed cola is $M$ g
$\Rightarrow \frac{1.05}{1}$ = $\frac{M}{300}$
Multiply by $300$ on both sides of the equation
$\Rightarrow \frac{1.05}{1}\times 300$ = $\frac{M}{300}\times 300$

$\Rightarrow M=315$ g
$\Rightarrow$ Mass of 300mL Ed cola is 315 g
Now, mass of a can of 300 mL of Ed cola is 315 + 35 = 350 g
