Answer:
0.3 Meters = 300 Millimeters
Explanation:
Multiply the length value by 1000
Hopefully, this helps! :D
O = C = O Straight because there is no solitary electrons on C
Answer:
a. [Na₂CrO₄] = 0.10 M
b. 0.017 moles of KBr
Explanation:
Molarity means a sort of concentration which indicates the moles of solute over 1L of solution.
We determine the moles of solute: 12.5 g / 162g/mol = 0.0771 moles
We convert the volume of solution from mL to L = 750 mL . 1L/1000mL = 0.750L
Molarity (mol/L) → 0.0771 mol / 0.750L = 0.10 M
b. In order to determine the moles of solute, with the molarity of solution and the volume we assume:
Molarity = moles of solute /volume of solution
Then, Molarity . Volume of solution (L) = moles of solute
We convert the volume of solution from mL to L = 150 mL . 1L/1000mL = 0.150L
0.112 mol/L . 0.150L = Moles of solute → 0.017 moles of KBr
Answer:
0.880 (0.88039867109 to be exact)
Explanation:
To convert from molecules to moles, simply divide by Avogadro's number which is 6.02 x 10^23
So, 5.30x10^23/6.02x10^23 = 0.880
