Una sustancia pesa 2 gramos y ocupa un volumen de 4 ml .Calcula su densidad en kg/m cubicos rapidooo pliiisss

2000kg/m³

Explanation:

Given parameters:

Mass of substance  = 2g

Volume  = 4mL

Unknown:

Density in kg/m³

Solution:

Density is the mass per given volume,

    Density  =

Since our answer must be in kg/m³;

    Volume in m³;

            4mL = 4 x 10⁻⁶m³

  Mass;

               2g  = 0.002kg

So;

 Density  = = 2000kg/m³

european union policies. the eu's long-term objective is to achieve levels of air quality that do not result in unacceptable impacts on, and risks to, human health and the environment. eu policies aim to reduce exposure to air pollution by reducing emissions and setting limits and target values for air quality.

the main environmental problems in western europe were: energy production/acid rain, nuclear power/waste, air pollution/climate, heavy metals, pesticides, water pollution, solid waste, and unforeseen accidents. many environmental problems are common to most european countries.
