Answer:
V(NH₃(g)) at STP = 0.8928 Liters ≅ 0.9 Liter (1 sig. fig)
Explanation:
Given 340g NH₃(g) => ?Volume at STP
Convert grams to moles by dividing by formula wt of ammonia
= 340g/17g/mole = 20 moles
1 mole of any gas at STP conditions (0°C, 1atm) occupies 22.41 Liters
∴ 20 moles NH₃(g) => 20moles/22.4Liters/mole
= 0.8928 Liters ≅ 0.9 Liter (1 sig. fig)
The density would be the same for the whole bar as well as one half of the bar. Density is a identity I believe, by this I mean that it stays the same no matter how little or how much of the same substance you have. Since density = mass / volume, half the bar has half of the weight as well as half of the volume of the whole bar, making the density the same.
For example, a block weighs 10 grams and has a volume of 5 ml. the density would be d = 10/5 or, d = 2g/ml
Half of the block weighs 5 grams and has a volume of 2.5 ml. The density is d = 5/2.5, or, d = 2 g/ml.
See, although there are different amounts of the same substance, their density is the same.
