Soal Latihan Massa Jenis Quiz - Quiz

Soal ini dirancang untuk menambah pemahaman tentang materi massa jenis.


Questions and Answers
  • 1. 

    Suatu benda dimasukkan dalam gelas ukur seperti gambar di samping! Jika volume benda ditunjukkan pada gambar di samping dengan satuan dalam cm3 , massa benda tersebut adalah 100 gram. Berapa massa jenis dari benda tersebut?

    • A.

      10 gr/cm3

    • B.

      20 gr/cm3

    • C.

      30 gr/cm3

    • D.

      40 gr/cm3

    Correct Answer
    B. 20 gr/cm3
    Explanation
    The given question states that a certain object is placed in a measuring glass, and its volume is shown in the adjacent picture in cm3. It is also mentioned that the mass of the object is 100 grams. We are asked to determine the density (mass per unit volume) of the object. To find the density, we divide the mass (100 grams) by the volume (given in cm3). The correct answer of 20 gr/cm3 is obtained by dividing 100 grams by the volume in cm3.

    Suatu benda berbentuk kubus memiliki massa jenis sebesar 20 kg/m3.  Massa benda tersebut adalah 540 kg, maka panjang sisi benda tersebut adalah 4 m.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The given statement is false. The density of an object is defined as the mass of the object divided by its volume. In this case, the density is given as 20 kg/m3 and the mass is given as 540 kg. To find the volume, we can rearrange the formula to volume = mass/density. Plugging in the values, we get volume = 540 kg / 20 kg/m3 = 27 m3. Since the object is in the shape of a cube, all sides have the same length. Therefore, the length of each side of the cube is the cube root of the volume, which is approximately 3. Therefore, the correct answer is False.

    Suatu benda massanya 79 g memiliki volume 10 cm3. Maka benda tersebut memiliki massa jenis dengan satuan dalam SI sebesar ________________

    Correct Answer
    79000 kg/m3
    79.000 kg/m3
    Explanation
    The given question asks for the specific gravity of an object with a mass of 79 g and a volume of 10 cm3. To find the specific gravity, we need to divide the mass by the volume. Converting the volume to m3 by dividing by 1000, we get 0.01 m3. Dividing the mass of 79 g by the volume of 0.01 m3 gives us a specific gravity of 79000 kg/m3. Therefore, the correct answer is 79000 kg/m3.

    Massa jenis merupakan pengukuran massa setiap satuan volume benda. Berikut ini yang merupakan satuan dari massa jenis adalah ....

    • A.

      Kg/m2

    • B.

      Kg/m3

    • C.

      Gr/m

    • D.

      Gr/cm3

    Correct Answer(s)
    B. Kg/m3
    D. Gr/cm3
    Explanation
    Massa jenis adalah pengukuran massa per satuan volume benda. Satuan yang digunakan untuk massa jenis adalah kg/m3 dan gr/cm3. Satuan kg/m2 dan gr/m tidak digunakan untuk mengukur massa jenis, karena kg/m2 adalah satuan untuk kepadatan massa permukaan dan gr/m adalah satuan untuk kepadatan massa panjang.
