Answer:
N2O5
Explanation:
IUPAC ID: Dinitrogen pentoxide
Molar mass: 108.01 g/mol
Density: 1.64 g/cm³
Answer:
0.68g/ml
Explanation:
The density of an object is its mass per unit volume. It is calculated using the formula
Density = mass / volume
Mass of stopper weighed = 4.8g
The volume of stopper can be got by subtracting the (volume of water) from the (volume of water+stopper) i.e.
= 39.2ml - 32.1ml
= 7.1ml
Volume of stopper = 7.1ml
Density of stopper= 4.8/7.1
Density= 0.676056
Therefore, the density of the stopper is 0.68g/ml
In general, SOLUBILITY<span> is an ability of a substance to dissolve. In the process of dissolving, the substance which is being dissolved is called a </span>solute<span> and the substance in which the solute is dissolved is called a </span>solvent.<span> A mixture of solute and solvent is called a </span><span>solution.</span>
