Question

if a plot weight (in g) vs. volume (in ml) for a metal gave the equation y= 13.41x and r^2=0.9981 what is the density of the metal?

Answer 1

ANS: 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

Answer 2

Answer:

13.41 g/mL is the density of the metal.

Explanation:

$y= 13.41\times x$

Slope intercept form of line:

$y = mx +c$

y = y, x= x m = 13.41 and c = 0

y= 13.41x + 0

Where y and x parameter as are the weights in grams and volume in milliliter respectively.

$\frac{Mass}{Voluime}=\frac{y}{x}=14.41 g/mL$

13.41 g/mL is the density of the metal.
