How many moles of oxygen are in HNO3?
Explanation: In 2 moles of nitric acid there are 2 moles of hydrogen atoms, 6 moles of oxygen atoms, and 2 moles of nitrogen atoms. Since the molar mass of nitrogen (atomic nitrogen!) is 14.01⋅g , we simply double the number.
What is the total mass of 2 moles of nitric acid?
According to the question we have to find out the total mass of 2 moles of nitric acid⇒ . The formula mass of nitric acid is:- atomic mass of H + atomic mass of N + 3(atomic mass of O). So, the answer is 126u.
How to find moles of nitric acid?
Divide the amount of HNO3 by 63 to determine how many moles there are in the amount of HNO3 you are using for your calculations. For example, if there are 1,000 grams of HNO3, divide 1000 by 63; the result will be the number of moles contained in 1,000 grams of HNO3, which is 15.87 moles.
How many atoms are present in 2.28 moles of nitric acid HNO3?
so one mole of it contains 3 mole oxygen atoms… 2.28 mole of it contains 3×2. 28 moles of oxygen atoms..
How many total atoms are in HNO3?
Answer Expert Verified Hey! We know that, composition of HNO3 is Hydrogen, Nitrogen and oxygen. Total number of atoms = 3+1+1=5 atoms are present in 1 molecule of HNO3.
What is the mass of 0.5 moles of water and ammonia atomic mass of H 1 O 16 N 14?
Thus, the mass of 0.5 mole of water (H2O) is 9 grams.
How many grams is 2 moles of HNO3?
In 2 moles of HNO3 H N O 3 , 28 grams of nitrogen are present. According to the definition of mole, 1 mole of a compound contains {eq}6.022 \times…
How many grams of nitric acid are in HNO3?
The density of 70% (w/w)Nitric acid is 1.413 g/ml at 25°C which means that the weight of the 1 ml of Nitric acid is 1.413 gram at 25°C. In simple words, 1 mole is equal to the atomic weight of the substance. For example, 1 mole of HNO3 is equal to 63.01 grams of HNO3 (molecular weight = 63.01).
How many atoms are present in a mole of HNO3?
Note the amounts of atoms of all the component in HNO3, which are 1 atom of Hydrogen, 1 atom of Nitrogen and 3 atoms of Oxygen. Multiply each of the atomic weights by the amount of atoms of each element contained in the compound. Add up the results to obtain the molar mass: 1 + 14 + (16 x 3) = 63 gr/mole.
