## What is mass of 3 moles of carbon?

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?

## How many atoms are in 3.0 moles of carbon?

Therefore there are **three atoms** in each molecule.

## What are 2 moles of carbon?

Explanation: In one mole of carbon, there are 6.02×1023 atoms. So in two moles, there will be twice that: **1.204×1024** .

## How many grams is 2.75 moles?

Therefore, the mass of 2.75 moles of CO2 is **121 grams**.

## What is the mass of 7 moles of carbon?

Therefore, the mass of 7 moles of carbon dioxide is equal to 7×44=**308g**.

## What is the formula for moles to grams?

Moles to grams example problem

Solution: Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KClO3 is 122.548 g/mol. **Multiply the given number of moles** (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.

## What is the mass of 1 mole of oxygen?

Solution — Mass of one mole of oxygen molecule (O2) = molecular mass of oxygen molecule (O2) in gram = **32 g**.

## How many molecules of CO2 will be there in 7 moles of CO2?

There are **4.2×1024 4.2 × 10 24 molecules** in 7 moles of CO2 .

## How many atoms do carbon have?

The value of the mole in precisely 12 grammes of pure carbon-12 is equal to the number of atoms. 12.00 g C-12 = 1 mol C-12 atoms = **6.022 x 10 ^{23} atoms**.
