Answer:
1 Oxygen atom has a mass of 16 grams, thus diatomic oxygen weights twice as much- 32 grams. Hence 32 grams is needed.
Answer:
0.238 M
Explanation:
A 17.00 mL sample of the dilute solution was found to contain 0.220 M ClO₃⁻(aq). The concentration is an intensive property, so the concentration in the 52.00 mL is also 0.220 M ClO₃⁻(aq). We can find the initial concentration of ClO₃⁻ using the dilution rule.
C₁.V₁ = C₂.V₂
C₁ × 24.00 mL = 0.220 M × 52.00 mL
C₁ = 0.477 M
The concentration of Pb(ClO₃)₂ is:

The layer of Earth that has partially melted material that moves the tectonic plates is Mantle. The correct option is C.
<h3>What are the layers of the Earth?</h3>
The Earth is divided into three layers: the crust, the mantle, and the core. This is the earth's outer layer, and it is composed primarily of solid rock, primarily basalt and granite. Oceanic crust and continental crust are the two types of crust.
The layer of Earth that has partially melted material that moves the tectonic plates is Mantle.
Thus, the correct option is C.
