Question

5g glucose is dissolved in 50 gram water. calculate the % w/w of glucose solution ??​

Answer 1

weight of glucose = 5g

weight of water = 50g

Weight of solution = weight of solute + weight of solvent

= 5 + 50 = 55g

w/w% = 5/55 *100

= 9.09%

Answer 2

Answer:

A = 10.588

so, A = 10.6gm

Explanation:

w/w = A/a + b × 100

so,

A/a + b × 100

now,

A/a + 60 × 100 = 15

∴A= 15/100 × (a + 60)

∴A= 3/20 × (a + 60)

∴A= 3/20a × 3/20 × 60

∴A= 3/20a + 9

∴A= 3a + 180/20

∴20A = 3a + 180

∴20A - 3a = 180

∴17A = 180

∴A = 180/17

∴A = 10.588

∴A = 10.6 ( approx. )

HOPE THIS FOUND HELFUL SO PLZZ GIVE ME RATES AND ALSO THANKS
