## How many atoms of carbon are in 2.5 mol of c2h6o?

We ignore the 6 hydrogen atoms because we're only interested in carbon. That leaves us with the C2 from the whole molecule. That's two carbons per molecule of Ethane, so you multiply the amount of moles from the initial question (In your case, 2.5) by the coefficient of the carbon. This becomes 2.5 X 2, which = 5.

Final answer: The mass of 2.50 mole of oxygen gas ( ) is 80 g.

## How many atoms of nitrogen are in 2.50 moles of NO2?

Therefore , there are 1. 505×1024 nitrogen atoms in 2.50 moles of NO2.

## How many grams of oxygen are there in 2.5 moles of oxygen atoms?

Solution : Number of moles =`("Mass ")/("Atomic mass ")` <br> ` therefore "Mass " = "Number of moles "xx "Atomic mass "` <br> `= 2.5xx16 <br> `= 40g. ` Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.

## How do you calculate atoms?

To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6.02 x 10^23.

## How many atoms are in 2 moles?

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

## What is the mass of 2.5 moles of carbon dioxide?

Mass of CO2 = number of moles x molecular mass of CO2. Hence, the mass of 2.5 moles of CO2 is 110 grams.

## What is the number of molecules in 2.5 moles of oxygen?

Expert-verified answer Therefore, a number of atoms present in 2.50 moles of oxygen are 3.01 ×10^24.

## How many particles are in 2.5 moles of h2o?

Stefan V. 1.5×1024 molecules.

## How do you calculate number of atoms?

# of atoms = N * (density) * volume / (Molecular Weight). N is a constant called Avogadro's number and its equal to 6.022*1023 atoms/mole. It can also be molecules per mole. In the above formula density times volume is just the mass.

## What is the mass of 2.5 mole of oxygen atoms?

40g Solution : Number of moles =`("Mass ")/("Atomic mass ")` <br> ` therefore "Mass " = "Number of moles "xx "Atomic mass "` <br> `= 2.5xx16 <br> `= 40g.

## What is the mass of a 2.50 mole of a gas?

Solution : Number of moles =`("Mass ")/("Atomic mass ")` <br> ` therefore "Mass " = "Number of moles "xx "Atomic mass "` <br> `= 2.5xx16 <br> `= 40g. ` Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.

## What is the mass of 2.5 gram atoms of oxygen?

40 g Mass of 2.5 g atoms of oxygen = 16 x 2.5 = 40 g.
