Answer:
Because iodine is a liquid, it has no melting point. Iodine is not an electrical conductor because each molecule consists of two iodine atoms connected by a covalent bond that cannot be stimulated sufficiently to transmit electrical energy.

<span>I'm assuming its cause the total mass is the same, changes between phases are physical... solid ice and liquid water have the same mass</span>
Answer:
17.6% is the percentage error
Explanation:
The percentage error is used to determine accuracy of a measurement (That is, how closely is the measure to the real or theoretical value). The equation is:
|Measure - Real| / Real * 100
In the problem, the measure was 22.7cm³ and real value is 19.3cm³. Solving for percentage error:
|22.7cm³ - 19.3cm³| / 19.3cm³ × 100
<h3>17.6% is the percentage error</h3>
Answer:
0.39 g/L is the concentration of albumin
Explanation:
We assume volumes additive
0.20 mL (volume of solute) + 2.84 ml (volume of solvent) = 3.04 mL (volume of solution)
Let's determine thee mass of solute. We first convert, the mL to L.
0.20 mL. 1 L/1000mL = 0.0002 L
We use the concentration to determine the mass → 0.0002 L . 6 g/L =
0.0012 g of albumin.
This is are the mass of solute in our solution, which has a volume of 3.04 mL. Let's convert the mL to L → 3.04mL. 1 L/1000mL = 0.00304 L
Concentration (g/L) = 0.0012 g / 0.00304 L = 0.39 g/L
