## What is the mass of 2.5 moles?

Answer: Cl2 contains two Cl atom so molar mass will be 35 . 5 x2 that is 71 GRAM means 0ne mole of Cl2 has 71 gram so 2.5 mol will be equal to 2.5×71. Gram.

## What is mass of 1.5 moles of O2?

Atomic mass of oxygen = 16 Mass of 1 mole of Oxygen molecule = 16 * 2 = 32 (Because, 1 molecule of oxygen has 2 oxygen atoms; Diatomic) So, Mass of 1.5 moles of Oxygen molecule = 1.5 * 32 = 48 gm.

## How many moles of oxygen atoms are present in 2.0 grams of oxygen gas O2?

How many moles of oxygen atoms are present in 2.0 g of oxygen O2? 1 mole of O2= 2 moles of O. So Moles of oxygen = 2 x 0.0625=0.13 moles of O.

## Is oxygen O2 or just O?

The difference between oxygen (O) and oxygen (O2 )is that the former is an oxygen atom while the latter consists of two O atoms bound together, forming a molecule also called oxygen. Oxygen is usually found as a diatomic gas. Therefore, we write it as O2.

## How do you find the mass of O2?

O2 is a diatomic molecule. The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu.

## What is the mass of 1.5 mole?

The relation between number of moles and mass is the number of moles is equal to given mass upon molar mass. Formula used: \$n=dfrac{m}{M}\$ where, n is number of moles, m is mass, M is molecular mass. m = 66 g. Hence the mass of 1.5 moles of \$C{{O}_{2}}\$ is 66 g.

## How many atoms are in 1.5 moles of O2?

Explanation: In the given formula, there is one carbon atom and there are two oxygen atoms. So, in total there are three atoms.

## What is the mass of 0.5 gram atom of oxygen?

Mass of 0.5gram atom of oxygen is 8gm

## How many molecules are in 2 moles of O2?

According to the concept, 1 mole contains 6.023 ×10^23 particles. So, 2moles of O2 contains 2× 6.023×10^23 molecule= 12.046 ×10^23 molecule .
