the atomic mass of nickel is 59.693 amu, and the atomic mass of chlorine is 35.45 amu. which molar mass is correct for nickel chloride?
A. 152.84 g/mol
B 129.59 g/mol
C. 188.29 g/mol
D. 94.14 g/mol
To find the molar mass of nickel chloride (NiCl2), we need to add the atomic masses of nickel and chlorine together.
Ni: 59.693 amu
Cl: 35.45 amu x 2 = 70.9 amu (since there are two chlorine atoms in each molecule of nickel chloride)
59.693 amu + 70.9 amu = 130.593 amu
Therefore, the correct molar mass for nickel chloride is closest to:
B. 129.59 g/mol
