CAN SOMEONE HELP WITH THIS QUESTION BELOW?✨

If a plot of weight (in g) vs. volume (in mL) for a metal gave the equation y=15.28x and R^2=0.9981, what is the density of the metal?

Answer 1

Answer:- density = 13.41 g/ml

Density (d) of a substance is the mass (m) occupied by it in a given volume (v).

Density mass/volume =

i.e. d = m/v

m = (d) v -----(1)

The given equation from the plot of weight vs volume is :

y = 13.41 x ---- (2)

Based on equations (1) and (2) we can deduce that the density of the metal is 13.41 g/ml
