What is the mass of 1 mole of Cl2 gas?
71g
1 mole of chlorine gas is Cl2=2×35.5g=71g=Grammolecularweight. Gram molecular weight is the mass in grams of the substance numerically equal to its molecular weight, chlorine is a halogen, and an elemental gas, and occurs as Cl2.
How do you find the molar mass of chlorine?
Use this formula mass: M (N) = Mr (Cl) · 1 mol = 35,453 g/mol. It is known that the chlorine molecule is diatomic – Cl2, then the relative atomic mass of the chlorine molecule will be equal to: Ar (Cl2) = 35,453 · 2 = 70,906 amu.
What is the mass of 1.50 moles of Cl2?
The molar mass of chlorine is 70.91 g/mol. Thus, the mass of chlorine needed is: m ( C l 2 ) = 1.50 mol ⋅ 70.91 g/mol = 106.4 m(Cl_2) = 1.50\text{ mol}\cdot70.
What are the number of moles of chlorine in 14.2 grams of Cl2?
Similarly, the mass of the chlorine molecule is given as \[14.2g\] and it is known that the molecular mass of the chlorine molecule is \[70.9g/mol\]. Thus, the mole present in the chlorine molecule can be calculated by using the mole formula. Thus, \[0.2mol\] is present in \[14.2g\]of chlorine.
How do I find molar mass?
The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol). The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms.
How do you calculate formula masses?
To calculate formula mass, multiply the subscript of each element in the formula by the element’s atomic weight (relative atomic mass) found on the periodic table. The unit for formula mass is either u or Da (Daltons). The amu has been replaced with u, even though it is still commonly used.
What is the mass of 2 moles of Cl2?
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.
