Answer:
According to mass and volume, block density is 2 g/ml
Explanation:
Density is a measure, usually used in physics and chemistry, that relates the mass and volume of a solid or compound.
In general terms, the density is directly proportional to the mass, and inversely proportional to the volume, so increasing the mass will also increase the density.
The formula used to calculate the density is
ρ =
Therefore, according to the mass and density of the block
ρ = = 2g/ml
Being the density of the block equal to 2 g/ml.

Explanation:
Given a food with a relative humidity of 81%, what is the water activity of that food?
The water activity of a food can be determined by using the formula:
water activity=relative humidity of food / 100
