Answer. therefore number of moles in 60 g of He = 15 moles..

## How many moles are in 2 grams of helium?

The answer is 4.002602. We assume you are converting between grams Helium and mole. You can view more details on each measurement unit: molecular weight of Helium or mol The molecular formula for Helium is He. The SI base unit for amount of substance is the mole.

## What is the number of moles in 52 gram of helium?

i) 52g of He (finding mole from mass). ii) 12.044×1023 number of He atoms (finding mole from number of particles). Additional Information: We cannot calculate the number of moles of a particular atom without knowing about the number of particles present or mass of the chemical element present.

## How do you calculate moles of helium?

- The given mass of Helium =52g.
- Thus the number of moles of Helium =givenmass/molarmass.
- =52/4.
- =13.

## How many moles are found in 40 L of helium gas?

Answer: 0.1784 moles of helium gas are contained in a 4.0-L flask at STP.

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

⇒ Number of moles which make up 20 grams of NaOH = (20 grams × 1 Mole)/(40 grams) = 0.5 moles.

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

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.

## How many moles are in 40 grams of NaOH?

Now take 120 grams NaOh and multiply this by 1 mol NaOH/ 40 grams NaOH. You can cancel out the grams and you have moles left. Now you do 120 x 1 / 40 and you get 3 moles of NaOH!
