Tolong dijawab ya sama caranya
1.sebuah log campuran padat memiliki massa jenis 8,0gr/cm³.Berapakah massa 0,5m³ campuran itu?
2.gas nitrogen memiliki massa jenis1,2×10-³gr/cm³.Berapa massa 0,25m³ gas nitrogen?

Answer 1

Nomor 1
p = m/V
m = pV
m = 8 x 0,5
m = 4 gram

Nomor 2
p = m/V
m = pV
m = 1,2 x 10⁻³ x 25 x 10⁻³
m = 30 x 10⁻⁶
m = 3 x 10⁻⁵ gram

Answer 2

Nomor 1
p = m/V
m = pV
m = 8 x 0,5
m = 4 gram

Nomor 2
p = m/V
m = pV
m = 1,2 x 10⁻³ x 25 x 10⁻³
m = 30 x 10⁻⁶
m = 3 x 10⁻⁵ gram
