Question

Arjun purchased 250 gm of glucose (C6H12O16) for Rs.40. Find the cost of glucose per mole.

Answer 1

Explanation:

Molar mass = c*6+h*12+o*16

= 12*6 + 1*12 + 16*16

= 72 + 12+ 256

molar mass = 340

now,

No. of moles : given mass/molar mass

= 250/340

= 0.71 moles

now we know that 0.71 moles cost 40

as we need to find cost of per mole

the cost is 50 (approx)
