Explanation:
The property of a substance to resist the flow of motion is known as viscosity. And, more is the density of a substance more will be its viscosity.
Whereas, lesser is the density of a substance then it is easy for the substance to move.
This means that more is the viscosity of a substance least will be its flow and when a substance has lesser viscosity then it will readily flow from one point to another.
Thus, we can conclude that the viscosities of several liquids are being compared. All the liquids are poured down a slope with equal path lengths. The liquid with the highest viscosity will reach the bottom last.

Answer: 43.2 grams
Explanation:
Given that,
Amount of moles of NH4 (n) = 2.4
Mass of NH4 in grams (m) = ?
For molar mass of NH4, use the molar masses of:
Nitrogen, N = 14g;
Hydrogen, H = 1g
NH4 = 14g + (1g x 4)
= 14g + 4g
= 18g/mol
Since, amount of moles = mass in grams / molar mass
2.4 mole = m / 18g/mol
m = 2.4 mole x 18g/mol
m = 43.2g
Thus, there are 43.2 grams in 2.4 moles of NH4.
