Answer:
When you prepared the solution, you will find that the molarity is 0.73M
Explanation:
First of all you should get by the periodic table, molar mass in the anhydrouds calcium.
CaCl2 · 0H20 = 110.98 g/m
Now we have to find out how many mols are 15 g.
So 15g / 110.98 g/m = 0.135 moles
This moles are in 185 ml of water. Molarity as you should know are moles of solute in 1 L of solution (either 1000 ml)
185 ml ______ 0.135 moles
1000 ml _____ x x = (1000*0.135) /185 = 0.730M
Answer:

if not sorry that's though the best answer
Explanation:
<u>The S.I unit for the given term:</u>
Mass is expressed in kilogram (kg)
temperature is expressed in kelvin (K)
Time is expressed in seconds (s)
Current is expressed in ampere (A)
<u>Explanation:</u>
<u>Current:
</u>
The current can be defined as the electric charge flow in the surface (means ratio of charge per unit time). It is measured in ampere (A)

<u>Temperature:
</u>
Kelvin (K), the general temperature unit in the international standard units system. The Kelvin scale is an absolute thermodynamic temperature scale that uses absolute zero, a temperature at which all thermal movements end with a classic description of thermodynamics.
<u>Mass:
</u>
Mass is both a feature of the objects weight and its resistance measurement to accelerate under the influence of pure force. The mass of the object also determines the gravitational force. The basic unit of mass is kilogram (kg)
<u>Time:
</u>
Time is the measurement of how much distance the objects takes to travel from one to another (speed). It is expressed in seconds (s).
A nucleoside has no natural group and is not a part of a nucleic acid.
Answer:
Molarity is similar to Concentration
Explanation:
Molarity (M) is the amount of solute in a solvent, similar to concentration.
