Answer:
Volume required from standard solution = 4675 mL
Explanation:
Given data:
Final volume = 75.0 mL
Final molarity = 130 M
Molarity of standard solution = 2.000 M
Volume required from standard solution = ?
Solution:
We use the formula,
C₁V₁ = C₂V₂
here,
C₁ = Molarity of standard solution
V₁ = Volume required from standard solution
C₂ = Final molarity
V₂ = Final volume
Now we will put the values in formula,
C₁V₁ = C₂V₂
2.000 M × V₁ = 130 M × 75.0 mL
V₁ = 9750 M. mL / 2.000 M
V₁ = 4675 mL
Answer:
D.atom 2 is not the same , because the mass number is different from atoms 1 and 2

Science can create new forms of energy that dont use coal for example; hydroelectricity, wind power, solar power, steam power, fusion, fission, etc.
Or science can create more efficient ways to use the resources.
