We started with 20ml of liquid and added another 480ml so the new volume of liquid is 20+480=500 ml. so the number of moles we started with is 0.02×0.25=0.005 moles. We haven’t added any more of the substance so we still have 0.005 moles but this is now dissolved in 500ml of liquid.

## How many mL are in a mol?

The answer is 1000. We assume you are converting between mole/litre and mole/milliliter. You can view more details on each measurement unit: mole/litre or mol/mL The SI derived unit for amount-of-substance concentration is the mole/cubic meter. 1 mole/cubic meter is equal to 0.001 mole/litre, or 1.0E-6 mol/mL.

## How do you calculate moles from concentration and mL?

You multiply the concentration (in moles per litre) by the volume in litres. The number of moles of a substance in one litre of solution is called its molarity. The official symbol for molarity is “c” (concentration), but most people use the symbol “M”. where n is the number of moles and V is the volume in litres.

## How many moles of NaOH are present in 500ml of a 0.02 M NaOH solution?

1 Answer. 1 mol of NaOH .

## How many moles of NaCl would there be in 1000 mL?

Therefore, if we divide 1000mL by 1000mL we will obtain a value of 1L. Boom, there would be 0.5 moles of NaCl!

## What is 35g in ML?

g to ml conversion table:

1 gram = 1 ml | 21 grams = 21 ml | 41 grams = 41 ml |
---|---|---|

13 grams = 13 ml | 33 grams = 33 ml | 53 grams = 53 ml |

14 grams = 14 ml | 34 grams = 34 ml | 54 grams = 54 ml |

15 grams = 15 ml | 35 grams = 35 ml | 55 grams = 55 ml |

16 grams = 16 ml | 36 grams = 36 ml | 56 grams = 56 ml |

## How many moles are in 1 ml of water?

Plugging in the mass of 1 mole of water and its density gives you: Volume = 18 grams / 1 gram/mL. Volume = 18 mL.

## What is the formula for calculating moles?

Number Of Moles Formula

- The formula for the number of moles formula is expressed as.
- Given.
- Number of moles formula is.
- Number of moles = Mass of substance / Mass of one mole.
- Number of moles = 95 / 86.94.

## How do you calculate moles on a calculator?

How to find moles?

- Measure the weight of your substance.
- Use a periodic table to find its atomic or molecular mass.
- Divide the weight by the atomic or molecular mass.
- Check your results with Omni Calculator.

## How do we calculate concentration?

Divide the mass of the solute by the total volume of the solution. Write out the equation C = m/V, where m is the mass of the solute and V is the total volume of the solution. Plug in the values you found for the mass and volume, and divide them to find the concentration of your solution.

## How can we prepare 0.1 N NaOH in 100 mL?

To make 0.1N NaOH solution = dissolve 40 grams of NaOH in 1L of water. For 100 ml of water = (4/1000) × 100 = 0.4 g of NaOH. Thus, the amount of NaOH required to prepare 100ml of 0.1N NaOH solution is 0.4 g of NaOH.

## How do you make a 40% NaOH solution?

So the equivalent weight of NaOH is 40. To make 1 N solution, dissolve 40.00 g of sodium hydroxide in water to make volume 1 liter.

## How many grams of NaOH are in 500 mL of a 1 M solution?

500 ml of a solution contains 20 grams of NaOH (mw = 40). Calculate the molarity of the solution. 20 gr of NaOH correspond to 0.5 moles which are contained in 0.5 liter of solution. In one liter of solution there will be (2)(0.5) = 1 mole and thus the solution is 1 M.

## How many moles are present in 1 liter of a 1m solution?

Answer and Explanation: Given- The volume of the solution is V = 1 L, and the molar concentration or molarity of the solution is M = 1 M. Thus, the total number of moles of the solution is 1 mole.
