The mass of a grain of salt is around 0.06 mg. How many grains of salt would be in 100 grams of salt?

Answer :

By solving a simple linear equation, we will see that there are 1666667 grains of salt on 100 grams

How many grains of salt would be in 100 grams?

We want to see how many grains of salt would be in 100 grams, only by knowing that the mass of a salt grain is 0.06 mg

Where:

1mg = 0.001g

Then the mass of x grains of salt, is given by the function below:

m(x) = x*0.06 mg

m(x) = x*0.00006 g

Now we want to find the value of x such that the mass is 100 grams, then we can write the equation:

x*0.00006 g = 100g

Solving that equation for x, we will get:

x = 100g/0.00006 g

x = 1666667

So there are about 1666667 grains of salt on 100 grams of salt.
