# What is the concentration of NaCl?

## 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.
