For the question "Calculate the mass(in grams)of calcium carbonate present in a 50.00mL sample of an aqueous calcium carbonate standard, assuming the standard is known to have a hardness of 75.0 ppm (hardness due to CaCO3).", the answer is <span>3740gCaCO3
For the question "</span>If the 50.00mL sample from problem 2 above was titrated with a 0.00500MEDTA, what volume (in milliliters) of EDTA solution would be needed to reach the endpoint?", the answer is <span>7470.L of EDTA.</span>
I believe it is D, as things are passing through
Answer: Rocks can tell paleoclimatologists the different climates that have existed during different geological ages.
Hope this helps!
The molarity of the diluted solution is 0.2706 M.
Given,
M₁ = 1.1 M
V₁ = 123 mL
V₂ = 500.0 mL
The dilution law formula is M₁V₁ = M₂V₂
1.1*123=M₂*500
M₂=0.2706 M
<h3 /><h3>Molarity </h3>
Molarity, a concentration unit used in chemistry, is determined by dividing the number of moles of a solute by the number of liters of solution. The phrase "molar concentration" (also known as "molarity," "amount concentration," or "substance concentration") refers to the amount of a substance per unit volume of solution and is used to describe the concentration of a chemical species, specifically a solute, in a solution. The most frequent measure of molarity in chemistry is the number of moles per liter, denoted by the unit symbol mol/L or mol/dm3 in SI units. A solution with a concentration of 1 mol/L is referred to as 1 molar, or 1 M.
