Question

What mass of the protein gelatin is needed to make 0.5 L of a 3 g/L gelatin solution? Show your work.

Answer 1

Answer:

m = 1.5 gram

Explanation:

Given that,

Density of protein gelatin, d = 3 g/L

The volume of protein gelatin, V = 0.5 L

We need to find the mass of the protein gelatin. The density of an object is given by :

d = m/V

Where

m is mass

$m=d\times V\\\\m=3\ g/L\times 0.5\ L\\\\m=1.5\ g$

So, the required mass is 1.5 gram.
