So after calculation, we found that value of
should be 501.7 grams.The conclusion is the mass
in the table above is 501.7 grams.
Explanation
This question involves calculating the remaining mass after loss due to some reasons (which aren't mentioned in the question). The total mass lost is given, and you can find mass 'X' subtracting it from the initial total mass. Please note, to do this process we need to ensure same units, the initial mass is given in grams, and the loss also in grams, so we're good to go!So, for timing at the 5th hours, the mass
can be represented by this formula:
From the table above, we know that the initial mass given is 510.7 grams while the water lost at 5 hours is 9.0 grams. Plug these numbers in,
Let's calculate that and see what is the correct value for
.
