What is the molar mass of Ca (ClO4) 2? 171.6 g/mol 203.6 g/mol 239.0 g/mol 279.1 g/mol

239.0 g/mol

Explanation:

The molar mass of a compound is the sum of all the molar masses of all the individual elements present in the compound.

The molar mass of Ca (ClO4) 2 can calculated as follows:

= 40 + 2[ 35.5 + (16x4) ]

40 + 2[ 35.5 + 64]

40 + 2[99.5]

40 + 199

239g/mol
