Answer:
Weight of boulder = 22,400 gram
Explanation:
Given:
Volume = 8,000 cm³
Density = 2.8
Find:
Weight of boulder
Computation:
Weight of boulder = Volume x Density
Weight of boulder = 8,000 x 2.8
Weight of boulder = 22,400 gram
Answer:
H2SO4 + Al(OH)3 = Al2(SO4)3 + H2O
Explanation:
Answer:
Explanation:
Since, the atomic mass of the elements is a characteristic property of the elements, you can use the data given, number of moles and mass in grams of the product, to calculate the atomic mass of the product, and then compare with the atomic masses of the elements (information foun in any periodic table).
<u>1) Atomic mass of the product</u>:
- Atomic mass = mass in grams / number of moles
- Atomic mass = 604.4 g / 6.3 mol = 95.94 g/mol ≈ 94.9 g/mol (rounded to three significant figures)
<u>2) Periodic table:</u>
- Molybdenum, Mo, the element with atomic number 42, has atomic mass equal to 95.94 g/mol.
<u>3) Conclusion</u>:
So, you can conclude safely that the element you have produced is Molybdenum.
