Answer: molar mass of NaCl is 58.5 gm/mol.
What is the mass of 2.5 mol?
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 the mass of 2.5 moles of water?
The amount of oxygen in 2.5 moles of water is 40 grams. The molecular formula of water is H₂O. 1 mole of water contains 1 mole of oxygen.
The mass of given amount of calcium carbonate is 250 grams.
What is the mass in grams of 2.5 mol?
And since we know that 1⋅mol of sodium has a mass of 22.99⋅g , we got a mass of 2.50⋅mol×22.99⋅g⋅mol−1=57.5⋅g with respect ot sodium.
Chlorine has two atoms, Cl2. Mass of 1 mole of Cl= 71g. Mass of 2.5 moles of Cl2= 2.5×71. =177.5 g.
What is the number of molecules in 2.5 moles of ammonia?
1.5×1024 molecules.
How many molecules are in 2.50 moles O2?
There are 6.022×1023 O atoms in a mole of O atoms. There are 6.022×1023 O2 molecules in a mole of O2.
Final answer:
The mass of 2.50 mole of oxygen gas ( ) is 80 g.
What is the moles of CaCO3?
390 Unit 6 Changes in Matter The formula mass of CaCO3 is 100.09 amu and, therefore, the molar mass of one mole of CaCO3 is 100.09 grams.
How many moles is NaCl?
One mol of NaCl (6.02 x1023 formulas) has a mass of 58.44 g.
What is the molar mass of NaCl?
For example, the molar mass of NaCl can be calculated for finding the atomic mass of sodium (22.99 g/mol) and the atomic mass of chlorine (35.45 g/mol) and combining them. The molar mass of NaCl is 58.44 g/mol.
Note that 6.022⋅1023 is also known as Avogadro’s number, and it can be referred to as the number of molecules in one mole of that substance. Also, I calculated 70.9 because 35.45 g/mol (the mass of one Chlorine atom) times 2 is 70.9 g/mol (Cl2 has two Chlorine atoms).
What is the mass of 3 moles of Cl2?
So the mass is 213 grams. So, the mass of 3 moles of chlorine molecule is 213gram.
