Your answer is Answer thank me later :) <3
Explanation:
Answer:
Step 1
1 of 2
V = m / D; V (nugget of gold) = 50 g / 5.0 g / cm 3 = 10 cm3; V (nugget of iron pyrite) = 50 g / 19 g / cm3 = 2.63 cm 3
Result
2 of 2
Due to these results you can conclude that nugget of gold which volume is 10 cm3 is bigger than volume of nugget of iron pyrite which is 2.63 cm3.

Answer:
Molecular formula = H₂S₂O₈
Explanation:
Given data:
Empirical formula = HSO₄
Formula mass = 194.13 amu
Molecular mass = ?
Solution:
Molecular formula = n × empirical formula
n = molar mass of the compound / empirical formula mass
Empirical formula mass = 1.008 + 32.065 + 16× 4
Empirical formula mass = 97.073
n = 194.13 / 97.073
n= 2
Molecular formula = n × empirical formula
Molecular formula = 2 (HSO₄)
Molecular formula = H₂S₂O₈
Answer:
The students should create a project in which they each look at a unique trait that each have (for example, detached ear lobes) and look at their parents to see if they too have this trait. To take it a step further, look at their grandparents for this trait, and ask them about their parents and if they have this trait, this could tell them whether the trait has always, been apparent within the family, if it skipped a generation, or the genetics of one parents were more dominant then the other.
