Explain with example the need of standard measurement system​

standard measurement system allows scientists to compare data and communicate with each other about their results. for example:ruler is a foot long and usually has inch and centimeter marks. A meter stick is a meter long and usually has foot, inches, and centimeter marks.

A standard system of measurement is very important because it helps us from making mistakes at the moment of doing calculations and correctly working...

A standard measurement system is important because it allows scientists to compare data and communicate with each other about their results. Metric System – is a measurement system based on the number 10.

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"
