Answer:
4.17 g/mL
Explanation:
In order to determine the density of the solid, we need to know both its mass and its volume.
<em>The mass </em>is already given to us by the problem, 45.0 g.
As for <em>the volume</em>, we can determine it by using <u>Archimedes' principle.</u> It states that the volume of water displaced by an object when submerged is equal to the object's volume.
- Water displaced = 75.8 mL - 65 mL = 10.8 mL
Finally we <u>calculate the density</u> of the solid:
- Density = mass / volume = 45.0 g / 10.8 mL
<span>Many life forms consist of a single cell. As well as simple bacteria, there are more complex organisms, known as protoctists. Unlike bacteria, they have complex internal structures, such as nuclei containing organized strands of genetic material called chromosomes. Most are single-celled, but some form colonies, with each cell usually remaining self-sufficient.</span>
This is mind numbing, but I got you.
3NaOH + 1FeCl<em>3</em> = 1Fe(OH)<em>3 </em>+ 3NaCl
3Mg + 2H<em>3</em>(PO)<em>4</em> = 1Mg(PO<em>4</em>)<em>2</em> + 3H<em>2</em>
Answer:
Plantae. Plants are multicellular and most don't move, although gametes of some plants move using cilia or flagella. Organelles including nucleus, chloroplasts are present, and cell walls are present. Nutrients are acquired by photosynthesis (they all require sunlight).
