## How many grams are in 1 mole of sodium hydroxide?

The molar mass tells you the mass of exactly one mole of a given substance. In this case, sodium hydroxide has a molar mass of **39.997 g mol−1** , which implies that one mole of sodium hydroxide has a mass of 39.997 g .

## How many grams are there in 0.2 moles of NaOH?

Amount of sodium hydroxide present in 500ml of 0.2M solutions is **4 gm**.

## How many moles are in 250 grams of nacl?

**7.32 mol**; 0.125 g.

## How many grams of NaOH are there in 250 ml of 0.4 M NaOH solution?

Approx. **4 g** of NaOH.

## What is the mass of 0.5 moles of NaOH?

In order to get grams, you’ll have to convert one of the volume units. I’ll do it this way: (0.5 moles/liter NaOH) * (0.2 liter end volume) * (40.0 g/mole) = amount to weigh out Now the units cancel, except for grams, giving **4.00 g**.

## How many grams are in 0.25 moles?

Extract the data from the question: moles = n = 0.25 mol. Check the data for consistency: Write the mathematical equation (mathematical formula): mass = moles × molar mass. Substitute the values into the equation and solve for mass (g): mass = m = 0.25 × 18.016 = **4.504 g**.

## How do you make a 0.2 molar NaOH 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.

## How many moles and grams of NaCl are present in 250 mL of 0.5 M NaCl solution?

From this we can conclude that the number of moles and grams of NaCl present in 250 mL of a 0.5 M NaCl solution is **0.125 and 7.32** respectively.

## How many moles and grams of NaCl are present in 250 mL?

Given, volume of solution is 250ml or 0.25 liter. So, number of mole of solute (NaCl) is 0.125mole present in solution . Hence, **7.3125 grams** of sodium chloride is present in 250mL.
