Seorang siswa ingin mengetahui m.jnis telur bbek dngan bantuan gram dapur. m jnis air dan garam berturut 1 g/cm& dan 10 g/cm*. jika telue melayang dlan lrutan dngan campuran 200ml air ditambah 5 sndok mkan gram dapur (1 sendok = 5 ml). m jenis telur adalah...g/cm*

Diket : massa jenis air = 1gr/cm³ massa jenis garam = 10gr/cm³ volume campuran = 200 ml volume garam = 25 ml Ditanya : massa jenis telur Jawab : massa jenis telur = massa jenis larutan = massa jenis larutan=massa telur/volume larutan(air+garam) =450/225 =2 a)massa telur = massa air (campuran) + massa garam = 200 + 250 =450 gr b) massa air = massa jenis air x volume air = 1x 200 = 200gr c) massa garam = massa jenis garam x volume garam = 25 x 10 = 250gr d) volume larutan = volume campuran (air) + volume garam = 200 + 25 = 225gr
massa jenis garam = 10gr/cm³
volume campuran = 200 ml
volume garam = 25 ml
Ditanya : massa jenis telur
Jawab : massa jenis telur = massa jenis larutan
= massa jenis larutan=massa telur/volume larutan(air+garam)
=450/225
=2
a)massa telur = massa air (campuran) + massa garam
= 200 + 250
=450 gr
b) massa air = massa jenis air x volume air
= 1x 200
= 200gr
c) massa garam = massa jenis garam x volume garam
= 25 x 10
= 250gr
d) volume larutan = volume campuran (air) + volume garam
= 200 + 25
= 225gr
Semoga dapat membantu :)
