Question

What is the mass of 3 moles of Barium acetate, Ba(C2H3O2)2

Answer 1

Molar masses of elements are –

• Ba = 137
• C=12
• H=1
• O=16

Mass of Barium acetate –

= 137 +( 12×2 +1×3+16×2)×2

= 137 + 59×2

=255

• Mass of 1 mole of Barium acetate is 255.Therefore, mass of 3 moles of Barium acetate will be( 3×255) = 765.
