1. How many moles of HNO3 will be produced when 0.65 grams of N2O5 reacts?
fiasKO [112]
The reaction equation:
N₂O₅ + H₂O → 2HNO₃

Moles N₂O₅ = 0.65 / (14 x 2 + 16 x 5)
Moles N₂O₅ = 6.02 x 10⁻³

Molar ratio N₂O₅ : HNO₃ = 1 : 2
Moles HNO₃ = 2 x 6.02 x 10⁻³

Moles HNO₃ = 0.012 mole

1. What volume is shown in the graduated cylinder below?
hram777 [196]

The volume shown in the graduated cylinder according to the image would 28 mL. Thus, the correct option would be C.

In the cylinder, the top of the liquid formed a concave meniscus with the walls of the cylinder. Thus, the bottom of the meniscus would be read as this is the normal rule.

The rule is such that for liquids that form concave meniscus with the walls of cylinders, the bottom of the meniscus is read while it is the top of the meniscus for liquids that form convex meniscus with the walls of cylinders.

Hence, looking at the image, the bottom of the concave is on the 28 mL mark on the cylinder.
