Answer:
NaNO3 (solubility = 89.0 g/100 g H2O)
Explanation:
The solubility of a specie is the amount of solute that will dissolve in one litre of the solvent. Solubility is usually expressed in units of molarity.
Now let us calculate the molarity of the NaNO3 (solubility = 89.0 g/100 g H2O)
Molar mass of NaNO3= 23+14+3(16)= 85gmol-1
Mass of solute=89.0g
Amount of solute= mass of NaNO3/molar mass of NaNO3
Amount of solute= 89.0g/85.0 gmol-1
= 1.0moles of NaNO3
Note that 100g of water=100cm^3 of water.
If 1.0 moles of NaNO3 dissolve in 100cm^3 or water therefore,
x moles of NaNO3 will dissolve in 1000cm^3 of water
x= 1.0 × 1000/ 100
x= 10.0 moles of NaNO3
Steroids are like hormones that
greatly influences bodily activities mostly in growth and function. These
functions may modify, change and control one’s body organs or system that’ll
vary in form, shape or structure due to these hormone-like compounds and also,
it can affect one’s psychological and neurological state. There are several
types of steroids. Examples can include:

1. </span>Sex steroids. These are can influence reproduction and
sex characteristics.</span>
<span><span>
2. </span>Anabolic steroids. Most abused in many athletic
activities. These steroids are used for muscle and bone growth. </span>
Mass = m = 40 grams
Volume = V = 9 cm³
Density = d = ?
Density is defined as the ratio of mass and volume.
So,
d = m/V
Using the values, we get
d = 40/9 = 4.44 g/cm³
This means the density of material would be 4.44 g/cm³
Answer: "exothermic" .
