The Earth, Mars or Jupiter should be denser than the Sun. Density is defined by mass and volume — components of object or matter. Although the sun is huge, it’s component is made up of mostly gas (hydrogen and helium). While Earth, though smaller than the Sun, contains heavier elements such as iron, sulfur, rocks, sediments, granite, basalt and water. Mars (composed of rocks and nutrients) and Jupiter (contains gases and compounds) as well are denser when compared to the Sun’s density. Referencing to our basic understanding of matter: solid and liquid should be heavier than gas.
Answer:
both are a number group of 12
Explanation:
dozen=12
15.00g of hydrated zinc sulfate loses 6.579 H₂O during heating what is the formula for the hydrate is ZnSO₄.7H₂O
Mass of anhydrous ZnSO₄ = 15.00 g - 6.579 g = 8.421 g
8.412 g of anhydrous ZnSO₄ = 6.579 g
molar mass of anhydrous ZnSO₄ = 161.47 g/mol
161.47 g of ZnSO₄ = (6.579 × 161.47) / 8.421
= 126 g
no. of moles of H₂O = mass / molar mass
= 126 / 18
= 7 molecules of H₂O
the formula for hydrate is ZnSO₄.7H₂O
Thus, 15.00g of hydrated zinc sulfate loses 6.579 H₂O during heating what is the formula for the hydrate is ZnSO₄.7H₂O
