Knowing that:
C = Common concentration
m = Mass of the solute
V = Volume of solution
Data:
C = 30 mg/mL
m = ?
v = 475 mL
Formula:
[tex]C = \frac{m}{v} [/tex]
Solving:
[tex]C = \frac{m}{v} [/tex]
[tex]30\:mg/\diagup\!\!\!\!m\diagup\!\!\!\!L = \frac{m}{475\:\diagup\!\!\!\!m\diagup\!\!\!\!L} [/tex]
[tex]m = 30*475[/tex]
[tex]\boxed{m= 14250\:mg}or\:\boxed{m\approx14.25\:g}\end{array}}\qquad\quad\checkmark[/tex]
Answer:
[tex]\underline{the\:total\:mass\:of\:insulin\:in\:the\:bottle\:is\:14.25\:grams}[/tex]
