Answer:
c. relative age
Explanation:
Relative age is a method of describing the age of rocks based on their order of appearance in the geologic column.
Events are denoted by their position in the column.
- The premise of most of the assumptions used relative age determination is based on stratigraphic laws.
- Absolute age gives numeric ages to rocks.
Since Luisa is comparing the age of people based on their position in her family, she is using the concept of relative dating.
It will get weeker and loose carbonation as well
After the water is boiled off, the mass is 9.7 grams, so find the weight of the water.
12.98 - 9.7 = 3.28g H2O
Find how many moles of CuSO4 and H2O you have.
If there are about 18g per mole of H2O
3.28/18 = .1822 moles of H2O
If there are about 160g per mole of CuSO4
9.7/160 = .0606 moles of CuSO4
.1822/.0606 = 3
Ratio of H2O to CuSO4 = 1:3
Formula
