Answer:
0.112 M.
Explanation:
- Molarity is the no. of moles of solute in a 1.0 L of the solution.
M = n/V.
<em>M = (mass/molar mass)solute x (1000/V of the solution).</em>
mass = 127.62 g.
molar mass = 286.138 g/mol.
V of the solution = 4.0 L = 4000.0 mL.
<em>∴ M = (mass/molar mass)solute x (1000/V of the solution)</em> = (127.62 g / 286.138 g/mol) x (1000 / 4000.0 mL) = <em>0.1115 M ≅ 0.112 M.</em>
HCL(g) it consists of covalently molecules which are bonded and they do not ionize.
Non-polar solvent molecules do not attract molecules of HCL which cause them to be ionized.
Answer:
7.2 meters per hour
Explanation:
It is given that,
The speed of a paramecium is 2,000 micrometers per second.
We need to find the speed of the paramecium in meters per hour.
We know that,
and
1 hour = 3600 seconds
Hence, the speed of the paramecium is 7.2 meters per hour.
