What mass of silver will occupy a volume of 87.75 mL?<br>The density of silver is 10.49 g/mL.​
Anastaziya [24]

Answer:

The mass of silver that will occupy a volume of 87.75 mL is 920.5 grams.

Explanation:

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space. In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

density=\frac{mass}{volume}

So the density of silver is 10.49 g / mL indicates that 10.49 g occupies a volume of 1 mL. Then a rule of three can be applied in the following way: if in 1 mL a mass of 10.49 g is occupied, in 87.75 mL how much mass will it occupy?

mass=\frac{87.75 mL*10.49 g}{1 mL}

mass= 920.5 g

<u><em> The mass of silver that will occupy a volume of 87.75 mL is 920.5 grams.</em></u>

Answer:

b. Diagnose most forms of mental illness.

Explanation:

Functional magnetic resonance imaging(fMRI) is a technology which measures and maps brains activity through observing small changes in blood flow.It is applied in examining the parts of the brain which handles vital processes, guide brain treatment process or predict effect of a disease on the brain.Through fMRI imaging, some brain abnormalities are identified which can not be detected using other imagery techniques.Currently scientists have developed neuromakers for different mental health conditions which MRI and other brain scans.Using these scans, tests are conducted and accurate mental health diagnosis is provided.
