Hello!
In my homework, it requires converting a 77 g / ml concentration into a mass volume percentage, but I don't know how.
Thanks for your help in advance!

Hi!
When we want to know the concentration of a solution in mass volume percentage (% m / v), we first want to put the concentration on a denominator of 100 ml. It will then be necessary to determine the quantity of solute in this volume.
Here is one way to solve this problem:
$$\frac{77 \;g}{1 \;ml}=\frac{x}{100 \; ml}\Rightarrow x = \frac{77 \;g \times 100 \; ml}{1 ml \;}$$
$$x = 7700 g$$
The concentration is therefore 7,700% m / v.
Hope this enlightens your understanding! Don't hesitate to ask other questions 😊
