## How many moles is 80 grams?

The question says that we need to calculate the moles in 80g of sulfur. So the number of moles present in 80grams of sulfur is 0.3125 moles.

## How many atoms are in 80 g of oxygen?

1 mol contains avogadro no. of atom i.e., 6.02×1023 atoms.

## How many moles are in 100g of oxygen?

There are 6.25 moles of oxygen in 100g of Water.

## How many number of gram atoms are present in 80 g of calcium?

where, \$n\$ is the number of moles of calcium, \$W\$ is the weight of calcium and \$M\$ is the molar mass of calcium. Therefore, the number of moles present in \$80g\$ of calcium is \$2,mol\$ . \$1,mole=6.022times {{10}^{23}}\$ particles. This number is known as Avogadro’s number \$({{N}_{A}})\$.

## Which of the following is correct for 1 mole methane?

One mole of methane specifies NA , Avogadro’s number of methane molecules, i.e. 6.022×1023 individual CH4 molecules. And thus it contains 4×6.022×1023 hydrogen atoms .

## How many moles are in 32g of oxygen?

And we know that When the given mass is divided by the molar mass of the gas. We will get the number of moles present in that gas so here it is =1. we get the answer as 1. So the number of moles present in 32 gram of oxygen is 1.
