## How much mass is in 3 moles of CO2?

Explanation: Carbon dioxide has a molar mass of 44.01⋅g⋅mol−1 …and so for the mass of a three quantity we take the product… **3⋅mol×**44.01⋅g⋅mol−1≡?? ⋅g …and in this quantity how many moles of carbon, and how moles of oxygen?

## Which molecules are there in 3 moles of CO2?

**1 Answer**

- 1 Mole is 6.02⋅1023 molecules.
- Therefore 3 Moles of Carbon Dioxide CO2 =3(6.02⋅1023) or 18.06⋅1023 molecules of CO2.
- There is one atom of Carbon and two atoms of Oxygen in each molecule of Carbon Dioxide CO2.
- (3 atoms) 18.06⋅1023 molecules =54.18⋅1023 atoms.
- 5.418⋅1024 atoms.

## What is the mass of 2 moles of carbon dioxide?

The answer is **24 g**.

## What is the mass in grams of 3 moles of water?

similarly 1 mole of water is equivalent to molecular mass of water x 3 that is 18×3=**54 gram**.

## How many items are in 3 moles?

A mole of anything contains 6.022×10**23** individual items of that something. You have 3 moles, so there are 3×6.022×1023 oxygen molecules .

## How many atoms are in 3 moles of o2?

1 mole of O₂ contains 6.022 × 10²³ atoms. Thus, 3 moles O₂ would contain 3 × 6.022 × 10²³ atoms. Therefore, 3 moles of O₂ contain **18.066 × 10²³ atoms**.

## How many carbon atoms are in 3 moles of CO2?

1 molecule of CO2 = 1 C atom + 2 O atom. So, 3 moles of CO2 contains (3 x 2 x 6.02 x 10*23) O atoms = **3.61 x 10*24 O atoms**.

## What is the mass of 8.70 moles of carbon?

8.70 moles CO_{2} x (2 moles of C_{4}H_{10}/8 moles of CO_{2}) = **2.175** moles of C_{4}H_{10} This gives us moles of C_{4}H_{10}. Now to calculate grams of C_{4}H_{10}, we need the molecular weight of this. Carbon – 12.01 There are four Carbons so 4(12.01) = 48.04 grams. Hydrogen – 1.008 There are 10 Hydrogens so 10(1.008) = 10.08 grams.
