What is the mass of 53 ml of ethanol, which has a density of 0.79 g/ml?

The answer is 41.87g

The volume of the ethanol is 53ml

The density of the ethanol is 0.79g/ml

The mass can be calculated as follows;

= mass × density

= 53 ×0.79

= 41.87

Hence the mass of the ethanol is 41.87g

m = 41.87 g

Explanation:

As we know that mass of an object is product of its density and volume

so we can say that

here we know that

also we know that

now by above formula we have

attach the statements so i can answer : )

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
