The molecular weight of water is <span>18.01528 g/mol.
So in 2.92 grams there are 2.92/</span>18.01528 = 0.1621 mol of particles.
1 mol contains 6,02214 × 10^<span>23 particles by definition.
So the nr of H2O molecules is </span>0.1621 * 6,02214 × 10^23 = 0,9761 × 10^23.
Every molecule has 2 H atoms, so you have to double that.
2* 0,9761 × 10^23 = 1.952 × 10^23.
The conductance of the electric current through the electrolytic solution increases with increase in concentration.
<h3>What is electrolysis?</h3>
The term electrolysis has to do with a situation in which liquids conduct electricity by the movement of ions.
The conductivity of the solution depends on the ions present in the solution. Thus, the conductance of the electric current through the electrolytic solution increases with increase in concentration.

Answer: With the cold front, warm air is rapidly forced upward (like the shavings) in advance of the actual front (the “cutter”), creating towering cumulus clouds, some hard showers and quite possibly a few gusty thunderstorms followed by a push of cooler and drier air in its wake.
Explanation:
Explanation:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
Density=mass/volume. Put the mass (2790g) over the volume (205mL)
Density= 2790g/205mL
Your answer should be in g/mL.
