Question

Tersedia satu liter aquadest, berapa gram yang harus ditambahkan agar mendapatkan gula dengan kadar 25% ?

Answer 1

Diketahui
massa air = 1kg (massajenis = 1 gr/mL )
kadar gula = 25% .
kadar air = 75%

kadar air = massa air/massa total x 100%
75 = 1 kg/massa total x 100
massa total = 100/75
= 4/3 kg..

massa air = 1 kg
massa glukosa = massa total - massa air
= 4/3 - 1
= 1/3 kg
= 0,3333 kg glukosa



semoga dapat membantu yah kak
