1 L ------- 1000 cm³
1.45 L ----- ???
1.45 * 1000 = 1450 cm³ ( volume )
Density = 0.710 g/cm³
mass = in Kg
m = D * V
m = 0.710 * 1450
m = 1029.5 g
1 Kg ------- 1000 g
kg -------- 1029.5 g
mass = 1029.5 / 1000
mass = 1.0295 Kg
hope this helps!
When water (H2O) is added to liquid isopropanol to form a solution, then polar isopropanol molecules are attracted to polar water molecules at the surface of the water. It forms a solution of rubbing alcohol.
<h3>Isopropanol and water in the solution</h3>
Isopropyl alcohol is water-soluble and forms hydrogen bonds with molecules of water (H2O).
When H2O is added to liquid isopropanol to form a solution, H2O spread in a uniform way in the solution.
These isopropanol molecules can surround H2O molecules, which are carried into the solution.

Answer:
Steel and cast iron
Explanation:
They are all metal but assuming that you are finding the best material for your pan i suggest going for steel or cast iron
Answer:
False
Explanation:
Atomic radius is defined as the distance between the nuclei of 2 identical atoms that are bonded together
Now, from periodic tables, chromium has a calculated atomic radius of 1.66 Å while iron has a calculated atomic radius of 1.56 Å
Thus, chromium has a bigger atomic radius than iron.
So the statement is false.
Dissolved organic substance present in natural water is a complex mixture compounds and contains most of the reduced carbon present in aquatic ecosytem . this can not be easily treated or disinfected by the conventional treatment . the experiments show that water sample with higher dissolved substance need higher cholrine demand . this is the reason that before disinfecting with chlorine ..... need to remove organic substance {{{ because it increase chlorine demand }}}
