Is the molar mass of oxygen 16 or 32?

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

Is the molar mass of oxygen 32?

Since both of these elements are diatomic in air – O2 and N2, the molar mass of oxygen gas is aprox. 32 g/mol and the molar mass of nitrogen gas is aprox.

### What is the mass of 3 molar mass Fe?

55.845 g/mol
2 Answers. Ernest Z. The molar mass of Fe³⁺ is 55.845 g/mol.

Is iron thiocyanate toxic?

Handling, Storage, and Precautions: metal thiocyanates on heating to decomposition, or on contact with acid or acid fumes, emit highly toxic fumes. Organic thiocyanates have low acute toxicity, but prolonged absorption may produce skin eruptions, running nose, nausea, and vomiting.

What is the mass of one molecule of oxygen in grams?

32 g
Solution — Mass of one mole of oxygen molecule (O2) = molecular mass of oxygen molecule (O2) in gram = 32 g. Mass of a single oxygen molecule = 32/1 × 1024 = 3.2 × 10-23g.

## What is the mass in grams of 5 atoms of oxygen?

Therefore, 5 moles × 32.0 g/mol = 160 grams is the mass (m) when there are 5 moles of O2 .

How many moles is 32 grams of oxygen?

of moles in 32 g of oxygen gas is 1. Explanation: The number of moles present in 32 gram of oxygen needs to be found out. As we know the molar mass of the gas or in this case oxygen is 2 16 which gives 32.

How many moles are there in 10 gram of oxygen?

Hence, there are 0.3125 moles of oxygen are present in 10 g of oxygen gas.

### What is the mass of oxygen in grams?

16.0 g
Oxygen has a molar mass of 16.0 g mol−1 , so 1 mole of oxygen atoms has a mass of 16.0 g .
