Question

Q5:
What is the molar mass of barium perchlorate, Ba(ClO4)2? (Ba = 137, Cl = 35.5, O = 16)

a) 189 g/mol
b) 272 g/mol
c) 336 g/mol
d) 240 g/mol

Answer 1

Answer:

option (b)272g/mol

Explanation:

it'll be mass of Ba+ 2Cl + 8O

=137+71+126

=272

Answer 2

C) 336 g/mol
Ba [Cl. (O4)]2
137 + [35.5 + (16*4)]2
137 + [35.5 + (64)]2
137 + [99.5]2
137 + 199
336 g/mol
