Data:
weight of water before heating = 0.349
weight of hydrate before heateing = 2.107
Formula:
Weight percent of water = [ (weight of water) / (weight of the hydrate) ] * 100
Solution:
Weight percent of water = [ 0.349 / 2.107] * 100 ≈ 16.6 %
Answer: 16.6%
Answer:
No.
Step-by-step explanation:
When looking at numbers after the decimal point, think of the numbers as real numbers.
In 1.25, think of the .25 as just 25.
Since this is after the decimal point, it is 25 of a 100.
Now, is 25 closer to 4 or not?
Of course, the number has a great distance from 4.
