## How many molecules are present in 80 grams of sodium hydroxide?

In 80 grams there will be **2 molecules** of NaOH, so mass of Sodium would be 23 x 2 = 46g.

## How many moles are there in 60 g of NaOH?

Answer : The number of moles in 60 g of NaOH is **1.5 moles**.

## 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 are present in 4 grams of sodium hydroxide?

=**0.10** (approx.)

## What is the mole formula?

Avogadro’s number is a very important relationship to remember: **1 mole = 6.022×1023 6.022 × 10 23 atoms**, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

## How many moles are present in 8g of sodium hydroxide?

The answer is **39.99711**.

## What is the formula for moles to grams?

In order to convert the moles of a substance to grams, you will need to **multiply the mole value of the substance by its molar mass**.

## How many moles is 17.6 g NaOH?

17.6 grams of sodium hydroxide are equal to **0.440 moles** of sodium hydroxide.

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

Answer: The answer is **39.99711**.

## How many grams of NaOH are in 3 moles of NaOH?

A 3.0 M solution of NaOH has 3.0 moles of NaOH per liter of solution. There are 0.25 L of solution (250mL⋅1L1000mL) , so there are 0.25L⋅3.0mol/L=0.75mol of NaOH. The molar mass of NaOH is 40.0 g/mol, so there are 0.75mol⋅40.0g/mol=**30g** of NaOH, 30.

## What is the mass of 0.5 mole of sodium hydroxide?

However, in expressing the concentration as M (molarity) the volume of the solution is also taken into account. Thus, 0.5 mole of NaOH represents simply **20 g** of the base while 0.5 M means 20 g of the base or NaOH dissolved per litre of the solution.
