    Question: calculate their densties in Si unit.

    200mg,0.0004m​³

    Answer:

    0.5 kg/m³

    Explanation:

    Applying,

    D = m/V…………………… Equation 1

    Where D = density, m = mass, V = volume.

    From the question,

    Given: m = 200 mg = (200/1000000) kg = 2.0×10⁻⁴ kg, V = 0.0004 m³ = 4.0×10⁻⁴ m³

    Substitute these values into equation 1

    D = (2.0×10⁻⁴ kg)/(4.0×10⁻⁴)

    D = 2/4

    D = 0.5 kg/m³

    Hence the density in S.I unit is 0.5 kg/m³
