Water is dissolved into n-butanol (a polar liquid). Which is the second step at the molecular level as water dissolves into n-bu
serg [7]

Answer:

Formation of intermolecular hydrogen bonding between water molecules and molecules of n-butanol

Explanation:

Low molecular weight alcohols are miscible with water in all proportions. The reason for this is that, when a low molecular weight alcohol is dissolved in water, intermolecular hydrogen bonds are formed between the low molecular weight alcohol and water molecules.

Low molecular weight alcohols such as n-butanol contain the polar -OH group which interacts with water via hydrogen bonding.

What is the mass of 11.4 L of NO2
kodGreya [7K]
At STP volume is 22.4 L

Molar mass NO₂ = 46.0 g/mol

1 mole ---------- 22.4 L
? mole ---------- 11.4 L

moles = 11.4 * 1 / 22.4

moles = 11.4 / 22.4

= 0.5089 moles of NO₂

Mass NO₂ :

moles NO₂ * molar mass

0.5089 * 46.0

= 23.4094 g of NO₂

hope this helps!
