Given the atomic mass of select elements, calculate the molar mass of each salt. element molar mass (g/mol) beryllium (be) 9.012 magnesium (mg) 24.31 cobalt (co) 58.93 cadmium (cd) 112.41 bromine (br) 79.90 match the numbers to the appropriate blanks in the sentences below. make certain each sentence is complete before submitting your answer. hints helpreset 88.91 gmol 104.21 gmol 168.81 gmol 138.83 gmol 184.11 gmol 218.73 gmol 192.31 gmol 272.21 gmol 1. the molar mass of cobr2 is . 2. the molar mass of bebr2 is . 3. the molar mass of mgbr2 is . 4. the molar mass of cdbr2 is .

Respuesta :

> the molar mass of CoBr2 is

CoBr2 = 58.93 + 2 (79.90)

CoBr2 = 218.73 g/mol

 

> the molar mass of BeBr2 is

BeBr2 = 9.012 + 2 (79.90)

BeBr2 = 168.812 g/mol

 

> the molar mass of MgBr2 is

MgBr2 = 24.31 + 2 (79.90)

MgBr2 = 184.11 g/mol

 

> the molar mass of CdBr2 is

CdBr2 = 24.31 + 2 (79.90)

CdBr2 = 272.21 g/mol
