Answer:
Molarity of solution is 0.0049 M
Explanation:
Molarity of a solution is the ratio of number of moles of solute to volume of solution in Liter
Number of moles is the ratio of mass to molecular weight of a compound.
Here is the solute.
448 mg of = 0.448 g of
So, 0.448 g of = moles of = 0.00245 moles of
Total volume of solution = 500 mL = 0.5 L
So, molarity of solution =
Answer:
Explanation:1 mole is equal to 1 moles CaCO3, or 100.0869 grams.
