Question

  1. a solid has a density of 1.05 g/ml. what would be the density in kg/l?
  2. a liter is equivalent to a cubic decimeter. a liquid with a density of 0.85 mg/kl would have what density in grams per milliliter?
  3. define density using the definitions of the terms in the equation.
  4. generally, rank the densities of the three common states of matter from lowest density to highest density

Step1: Convert grams to kilograms

We know that $1\ kg = 1000\ g$, so $1\ g=\frac{1}{1000}\ kg$. Also, $1\ L = 1000\ mL$, so $1\ mL=\frac{1}{1000}\ L$. Given density $
ho = 1.05\ g/mL$, substituting the conversion factors: $
ho=1.05\times\frac{1/1000\ kg}{1/1000\ L}$.

Step2: Simplify the expression

$
ho = 1.05\ kg/L$.

Step1: Recall the conversion factors

$1\ Mg = 10^{6}\ g$ and $1\ kL=10^{3}\ L = 10^{6}\ mL$. Given density $
ho = 0.85\ Mg/kL$, substitute the conversion - factors: $
ho=0.85\times\frac{10^{6}\ g}{10^{6}\ mL}$.

Step2: Simplify the expression

$
ho = 0.85\ g/mL$.

Brief Explanations

Density ($
ho$) is defined as the mass ($m$) of a substance per unit volume ($V$). Mathematically, $
ho=\frac{m}{V}$, where mass is the amount of matter in an object and volume is the amount of space the object occupies.

Answer:

$1.05\ kg/L$
