Question

5) Determine the mass in grams of the following:
a. 2.00 mol N b. 3.01*10^23 atoms Cl

Answer 1

5a) mass N = 2 moles x 14 g/mol = 28 g

5b) mass of Cl:

1 mol Cl = 6.02 x 10^23 atoms
x mol = 3.01 x 10^23 atoms

x= 0.5 moles

masss of Cl = 0.5 moles x 35.5 g/mol = 17.75 g

Good luck!

Answer 2

a. Take atomic mass of N, multiply by 2
b. Take atomic mass of Cl, divide by 2 [3.01*10^23 is half Avogadro's number, therefore half a mole]

Answer 3

I do not know I smoke to much weed so **** off *****.
