## How many grams of NaOH are in 250mL of a 3.0 m NaOH solution?

29.99 g

Explanation: It’s a 3.0 M solution so 1 litre of solution contains 3 moles of NaOH. 250 ml of solution therefore contains 0.25 x 3 = 0.75 moles of NaOH. The molar mass of NaOH is 39.9971 g/mol, so 250 ml of this solution contains 0.75 x 39.9971 = 29.99 g, or if you round it up 30.0 g.

**How do you make 0.1 NaOH?**

There are two ways to prepare 0.1M Sodium Hydroxide (NaOH) solution….0.1M NaOH solution is 10 times less concentrated than 1M NaOH solution.

- Take a 1000ml dry and cleaned volumetric flask.
- Transfer 10ml of 1M NaOH solution into 1000ml volumetric flask.
- Make up the volume upto 1000ml with distilled water and mixed well.

### What mass of NaOH is contained in 250 ml of a 0.4 M solution?

Approx. 4 g of NaOH.

**How many grams of NaOH are there in 500 ml of 0.125 M NaOH?**

The mass of NaOH needed to prepare 500 mL of 0.125 M NaOH is 2.5 g.

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

The Answer is 8 grams of NaOH. Molarity = Mass of solute × 1000/(Molar mass of solute × Volume of solution in mL). It is given that M=0.4 and V= 500mL.

**How many grams are in a 250ml solution of NaOH?**

Since the molecular weight of NaOH is 40.00, a 0.5M solution contains 20.00 grams per liter or 5 grams in 0.25 L (i.e. 250mL). How do you prepare 100 ml of 1.0 M NaOH from a stock solution of 3.0 M NaOH?

### What is the molarity of 8 grams of NaOH?

The Answer is 8 grams of NaOH. Molarity = Mass of solute × 1000/ (Molar mass of solute × Volume of solution in mL). It is given that M=0.4 and V= 500mL. 0.4=Mass of NaOH ×1000/ (40×500).

**How do you calculate moles of NaOH in N AOH?**

Thus nNaOH = 500 ×10−3L × 0.175 ⋅ mol ⋅ L−1 = 0.0875 ⋅ mol. (i.e., moles = volume × concentration ); this is certainly consistent dimensionally. We thus have a quantity in moles of N aOH. All we have to do is multiply this molar quantity by the molar mass:

## What is the volume of 16G of NaOH in DM3?

40 x 0.4 g = 16g of sodium hydroxide pellets should be dissolved in water and the total volume of the solution made up to 1 litre (dm3), once the mixture has cooled to room temperature. How many grams are needed to make 10\% of NaOH?
