how many times larger is the mass of an average grain of rock song than the mass of an average grain of table salt

Answers

Answer:

Step-by-step explanation:

The sample answer for edmentum is: The first factor of the mass of an average grain of rock salt is 40 times the first factor of the mass of an average grain of table salt. So, the mass of an average grain of rock salt is 40 times greater than the mass of an average grain of table salt.

The mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt

What is scale factor?

Scale factor is used to compare the size of two objects. Mathematically, we can write -

{K} = S{O1}/S{O2}

13 mg

Given is to compare the mass of an average grain of rock sand than the mass of an average grain of table salt.

The mass of an average grain of rock sand is : 13 mg

The mass of an average grain of table salt is : 0.3 mg

So, we can write that -

{K} = M{rock sand}/M{table salt}

{K} = 13/0.3

{K} = 130/3

{K} = 43.4

So, it can be concluded that the mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt.

Therefore, the mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt.
