Why is one method more precise than the other? Method B is less precise because the absolute uncertainty in the 1‑mL pipet is 0.006 mL,0.006 mL, which is smaller than the uncertainties of the other glassware. Method B is more precise because the absolute uncertainty in the 1‑mL pipet is 0.006 mL,0.006 mL, which is smaller than the uncertainties of the other glassware. Method B is less precise because the percent relative uncertainty in the 1‑mL pipet is 0.6%,0.6%, which is 33 times larger than the uncertainties of the other glassware. Method B is more precise because the percent relative uncertainty in the 1‑mL pipet is 0.6%,0.6%, which is 33 times larger than the uncertainties of the other glassware.

"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"

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
