How do you do a 1 1000 dilution?

How do you do a 1 1000 dilution?

You could make 1/1,000 by adding 1 microliter of sample to 0.999 ml diluent. Why is that a poor choice? Because you can’t measure 1 microliter (or even 10 microliters) accurately with ordinary pipeters. So, make three serial 1/10 dilutions (0.1 ml [100 microliters] into 0.9 ml): 1/10 x 1/10 x 1/10 = 1/1,000.

How do you calculate water usage?

Meters record how much water has been used. Deducting the current meter reading from the previous reading will tell you how many units of water you have used since your last meter reading. To determine your dollar amount of water consumption, multiply the units used by your current water rate.

How do you make a 0.2 molar solution?

Use sodium hydroxide’s molar mass to determine how many grams would contain this many moles. If you add 0.64 g of solid sodium hydroxide to the stock solution you’ll get a 0.2-M solution of (approximately) the same volume.

What is the concentration of 800 ml of solution?

800. mL of solution has a concentration of 3.0 M. How much water needs to be added to dilute the solution to 1.9 M? As you know, a dilution is used to decrease the concentration of a given solution.

What is the volume of the solution when adding water and ethanol?

For example, adding 50 mL of water to 50 mL of water will result in a total volume of 100 mL, and adding 75 mL of 100\% ethanol to 75 mL of 100\% ethanol will result in a total volume of 150 mL. However, when mixing miscible liquids (such as water and ethanol), the final volume of solution is not exactly equal to the sum of the individual volumes.

How do you calculate amount of concentration in moles?

Amount (in moles) = amount (in g) molar mass (in g.mol-1) Concentration (M) = amount (in mol) volume (in L) Concentration (M) = 1 mol 1 L = 58.44g 1 L = 5.844g 100 mL = 5.8\% (w/v) Essential Maths for Medics and Vets Reference Materials Module 2. Amount and Concentration.

What is the amount concentration volume of 10ml of salt?

Answer: amount concentration volume = amount concentration volume= × Amount in 10ml = 10ml x 1mol.L-1 x 0.001 L.mL-1 = 0.01mol So imagine that you are taking 10ml which has 0.01mol salt in it, and you put it into a total volume of 100ml.
