Answer:
0.5 M
Explanation:
Molar concentration : M = n/v
n = moles of solute
v = liters of solution
Hence, 5.0 / 10.0 = 0.5 M

Answer:
The concentration of the diluted solution is 3.75 M
Explanation:
Step 1: Data given
Volume of a stock solution = 75 mL = 0.075 L
The molarity of stock solution = 5.0 M
We add 25 mL, The total volume is 100 mL = 0.100 L
Step 2: Calculate the concentration of the diluted solution
C1*V1 = C2*V2
⇒with C1 = the initial concentration = 5.0 M
⇒with V1 = the initial volume = 0.075 L
⇒with C2 = the new concentration = TO BE DETERMINED
⇒with V2 = the diluted volume = 0.100 L
5.0 M * 0.075 L = C2 * 0.100L
C2 = (5.0M * 0.075 L) / 0.100 L
C2 = 3.75 M
The concentration of the diluted solution is 3.75 M
Answer:
2024.1g
Explanation:
Given parameters:
Number of moles of Na = 34.6moles
Unknown:
Mass of product formed = ?
Solution:
We must first establish the reaction equation as shown below;
2Na + Cl₂ → 2NaCl
We solve from the known to the unknown specie;
2 moles of Na produced 2 moles of NaCl
34.6moles of Na will produce 34.6moles of NaCl
Now to find the mass of NaCl;
mass = number of moles x molar mass = 34.6 x (23 + 35.5) = 2024.1g
