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

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.

  1. Take a 1000ml dry and cleaned volumetric flask.
  2. Transfer 10ml of 1M NaOH solution into 1000ml volumetric flask.
  3. 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?
