What is the concentration of NaCl?

We do this by dividing by the molecular weight of NaCl (58.4 g/mole). Then, we divide the number of moles by the total solution volume to get concentration. The NaCl solution is a 0.1 M solution.

How do you find the concentration of NaCl solution?

NaCl = 23.0 g/mol + 35.5 g/mol = 58.5 g/mol. Total number of moles = (1 mole / 58.5 g) * 6 g = 0.62 moles.

How do you make a 1 mM solution?

A 1M solution would consist of 342.3 grams sucrose in one liter final volume. A concentration of 70 mM is the same as 0.07 moles per liter. Take 0.07 moles/liter times 342.3 grams per mole and you have 23.96 grams needed per liter. To make 200 milliliters of your solution multiply grams/liter by liters needed.

What is millimolar solution?

millimole = 1/1000 of a mole. millimolar = mM = term used to discuss molarity in thousandths of a mole (e.g., a 20 mM. solution contains 20/1000 = 0.02 moles per liter) w/v = weight (of solute) per final solution volume.

What is the concentration of the salt solution?

Salt concentration in slightly saline water is around 1,000 to 3,000 ppm (0.1–0.3%), in moderately saline water 3,000 to 10,000 ppm (0.3–1%) and in highly saline water 10,000 to 35,000 ppm (1–3.5%). Seawater has a salinity of roughly 35,000 ppm, equivalent to 35 grams of salt per one liter (or kilogram) of water.

What is the concentration of salt?

about 35 parts per thousand
The concentration of salt in seawater (its salinity) is about 35 parts per thousand; in other words, about 3.5% of the weight of seawater comes from the dissolved salts. In a cubic mile of seawater, the weight of the salt (as sodium chloride) would be about 120 million tons.

How do you calculate salt concentration?

Divide the mass of the first dissolved component by the solution mass, and then multiply the result by 100 to calculate the mass percentage. In our example, the first dissolved compound is NaCl; the mass percent is (10 g / 136 g) x 100 percent = 7.35 percent.
