## How many moles of NaOH are contained in 30ml of its 0.15 M solution?

= 0.15 / 1000 X 27 moles. = 0.004 Moles.

## How many moles of NaOH are present in 25ml of 0.015 m NaOH?

=0.045 (ans).

## How many moles are in 15 mL of NaOH?

Equation 1

How many moles of NaOH would be present in 15.0 mL? 5.00 moles/L X 0.0150 L= 7.50 X10^{–}^{2} moles of NaOH.

## How many moles of NaOH are there in 500 mL of a 2.0 M solution?

1 mol of NaOH .

## How many moles of NaOH are present in its 3m solution?

To calculate the moles of solute, substitute the values of molarity and volume in the given formula. Therefore, the 0.03 moles of NaOH are present in 10.0 mL of a 3.00 M solution. Note: Make sure to convert the volume given in milliliter into liters as the molarity is calculated in terms of liters.

## How many moles of NaOH are present in 90g of NaOH?

There are 2.25 moles of NaOH in 90g of NaOH.

## What volume of 0.15 m NaOH will contain 0.184 g NaOH?

∴ Volume of solution =(0.184g)(0.15mol L-1)×(40g mol-1)=0.0307L=30.7mL.

## How many moles are in 20 ml of NaOH?

You are given 1 Molar NaOH. This is in moles per liter. However, if you consider the density approach, 1M of NaOH has a density of 1.04 g/ml so 20 ml is 20 x 1.04 g = 20.8 g/40 g/mol (MW of NaOH) that is going to yield 520 mmol of NaOH in 20 mll of 1 M NaOH.

## How do you make a 15% NaOH solution?

15 grams of sodium hydroxide is present in 100 grams of solution. So, to make 50 g of 15%(w/w) sodium hydroxide solution, 47.2 mL of water is needed under experimental conditions.

## How many moles are in NaOH?

First, the molar mass of NaOH is 39.997 g/mol. Divide the mass by the molar mass and you’ll have the equation: 60 g / 39.997 g/mol. The grams cancel and you are left with 1.50 moles of NaOH.

## How many grams of NaOH are present in 250 mL of NaOH solution?

So 250mL of a 0.5m solution is 5.0g of NaOH.

## How many grams of NaOH are there in 500 mL of a 0.125 M NaOH solution?

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

## How do you prepare 500.00 mL of a 0.1 m NaOH solution from NaOH s )?

Dissolve 20 gms of NaOH in 500 ml of water to prepare 500 ml 1N NaOH soln.
