We can do so by using a simple unitary method. Hence, the number of grams of sodium is present in 2 moles is 46g . Additional Information: The number 6.022×1023 is commonly referred to as the constant of Avogadro and is often denoted by the ‘ NA ‘ symbol.

## How much does 2 moles of sodium weigh?

Explanation: Sodium metal has a molar mass of 22.99 g⋅mol−1 . Thus if there is a 2 mol quantity the mass is: 2⋅mol ×22.99⋅g⋅mol−1 = ??

## How many grams are in one mole of sodium?

And whereas one sodium atom has an approximate mass of 23 u, 1 mol of Na atoms has an approximate mass of 23 grams. One mole of a substance has the same mass in grams that one atom or molecule has in atomic mass units.

…

1 Na molar mass: | 22.99 g |
---|---|

1 Cl molar mass: | 35.45 g |

Total: | 58.44 g |

## What is the number of sodium atoms present in 2 mole of sodium?

If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms.

## How many grams are in a 1.5 mole sample of sodium?

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Sodium, or 22.98977 grams.

## How many grams are there in 10 moles of sodium?

The unit is denoted by mol. ∴ The mass of 10 moles of sodium sulphite = 1260 grams.

## How do you calculate moles of sodium?

To convert between grams and moles, you would use the substance’s molar mass. To go from grams to moles, divide the grams by the molar mass. 600 g58.443 g/mol = 10.27 mol of NaCl. It has been found that 1 mol of any gas at STP (Standard Temperature and Pressure = 0 °C and 1 atm) occupies 22.4 L.

## How many moles are in 10 grams of NaOH?

The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide. The SI base unit for amount of substance is the mole.

## What is the grams of sodium?

The Elements, sorted by Atomic Mass

Atomic Number | Symbol | Atomic Weight (amu, g/mol) |
---|---|---|

10 | Ne | 20.179 |

11 | Na | 22.98977 |

12 | Mg | 24.305 |

13 | Al | 26.98154 |

## How many moles are there in 5 gram of sodium?

Moles = mass / molar mass

So, 0.125 moles are present in 5g of NaOH.

## How many atoms are present in 4 moles of sodium?

So we are going to take our known value of 4 moles, and multiply by 6.02 x 10^23 (Avogadro’s number) and we will get the number of atoms that are in 4 moles. There are 2.4 x 10^24 atoms of Na in 4.0 moles.

## How many atoms are in a mole of sodium?

Answer: Then, multiply the number of moles of Na by the conversion factor 6.02214179×1023 atoms Na/ 1 mol Na, with 6.02214179×1023 atoms being the number of atoms in one mole of Na (Avogadro’s constant), which then allows the cancelation of moles, leaving the number of atoms of Na.

## How many atoms are in 3 moles of sodium?

3 mol Na × (6.022×10^23 atoms Na/1mol Na) = 1.807×10^24 atoms Na.

## What is the mass of 2.5 moles of sodium?

And since we know that 1⋅mol of sodium has a mass of 22.99⋅g , we got a mass of 2.50⋅mol×22.99⋅g⋅mol−1=57.5⋅g with respect ot sodium.

## How many moles are in 50 grams of h2o?

1 Answer. There are 3 moles of O in 50 g.
