## How do you convert mol to dm?

The relative formula mass of the solute is used to convert between mol/dm 3 and g/dm 3:

- to convert from mol/dm 3 to g/dm 3, multiply by the relative formula mass.
- to convert from g/dm 3 to mol/dm 3, divide by the relative formula mass.

**Is mol dm 3 THE SAME AS mol L 1?**

The units moles per liter (mol liter–1) or moles per cubic decimeter (mol dm–3) are used to express molar concentration. They are equivalent (since 1 dm–3 = 1 liter).

**How do you convert molarity to mol dm3?**

A solution that contains 1 mole of solute per dm3 is often called a molar solution. Molarity in mol per dm3 = moles solute dissolved / volume of solvent in dm3.

### Is G dm3 the same as mol dm 3?

A measure of the amount of moles in a given volume. Conc. (mol dm-3) = moles (mol) Volume (dm3) Conc. (g dm-3) = mass (g) Volume (dm3) Page 2 Calculations in Chemistry MOLES A measure of the amount of substance. Number of = mass (m) moles (n) Molar mass (Mr) Mass is measured in grams.

**How do you convert moles to dm3?**

To find the number of moles in a solution, multiply the concentration by the volume in dm3. Again, if the volume is in cm3, divide the volume by 1000 first to convert it into dm3.

**How do you convert mol L to GL?**

To convert to g L-1 you multiply the concentration by the molar mass; = 0.118 mol L-1 x 55.9 g mol-1 = 6.60 g L-1 (3 s.f.)

## What is 1m in mol dm 3?

A solution that contains 1 mole of solute per 1 liter of solution (1 mol/L) is called “one Molar” or 1 M. The unit mol/L can be converted to mol/m3 using the following equation: 1 mol/L = 1 mol/dm3 = 1 mol dm−3 = 1 M = 1000 mol/m3.

**What is a dm 3?**

Dm3 may stand for: Cubic decimetre ( ), a volume unit which is exactly equivalent to a litre.

**What is the volume of acid in DM3?**

Volume of acid = 100 ÷ 1000 = 0.1 dm 3. Concentration of acid = 0.02 mol ÷ 0.1 dm 3 = 0.2 mol/dm 3. Converting between units

### How to convert from g/dm3 to molar mass?

to convert from g/dm 3 to mol/dm 3, divide by the relative formula mass; Remember: the molar mass is the A r or M r in grams per mol. Example. Calculate the concentration of 0.1 mol/dm 3 sodium

**How many moles of sodium hydroxide are in 2 dm3 of water?**

0.5 mol of sodium hydroxide is dissolved in 2 dm3 of water. Calculate the concentration of the sodium hydroxide solution formed. \\ [Concentration~in~mol/dm^ {3} = \\frac {amount~of~solute~in~mol} {volume~in~dm^ {3}}\\]

**What is the pH of a solution of sulphuric acid?**

The result is that the pH of the 0.1 mol dm -3 acid is about 0.98. If sulphuric acid were monobasic the expected pH would be 1; the second ionisation makes very little difference. Sulphuric acid behaves essentially as a monobasic acid as far as the pH of the solution is concerned. Consider a 0.1 mol dm -3 solution of sulphuric acid.
