## How many moles are in NaOH?

Determining the Molar Mass of a Compound

The molar mass of the compound NaOH is **40 g/mol**.

## How many moles are in 80g of NaOH?

= 80 / 40= **2 mol** .

## How many moles are in 30g of NaOH?

The molar mass of NaOH is 40.0 g/mol, so there are **0.75mol**⋅40.0g/mol=30g of NaOH, 30.

## How many moles of NaOH are present in 27 ml of 0.015 M NaOH?

=**0.045** (ans).

## 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 are in 11.5 g of NaOH?

The molar mass of Na is equal to 23g/mol. The formula to find out the number of moles is given by . Therefore the number of moles in 11.5g of sodium or Na is equal to which gives us **0.5**.

## How many moles of NaOH are present in 160g of NaOH?

Question = Calculate the moles of Sodium hydroxide contained in 160 g of it. Answer = 160 g of Sodium hydroxide. 160 g of Sodium hydroxide = 1 mol × 160 / 40 = **4 mol**.

## How many moles of sodium hydroxide NaOH are present in 200 g NaOH?

200 g / 40 g /mol =**5 mol**.

## What is the number of moles in 10g of NaOH?

Answer: The answer is **39.99711**.

## How many particles are in 7.5 moles?

Explanation: And Avogadro’s number , 6.022×1023⋅mol−1 specifies a molar quantity…… And so 7.5⋅mol×6.022×1023⋅mol−1≅**4.5×1024 sulfur atoms** .

## 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**.
