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.

Suppose you start with one liter of vinegar and repeatedly remove 0.08 L, replace with water, mix, and repeat. a. Find a formula
Bumek [7]

Answer:

0.92^n

Explanation:

Given that :

Initial amount of vinegar = 1 Litre

Number of litres removed repeatedly = 0.08 Litre

Since the amount removed each time is constant, then ;

Initial % = 100% = 100/100 = 1

. Using the relation :

Amount of vinegar in mixture :

Initial * (1 - amount removed / initial amount)^n

n = number of times repeated

1 * (1 - 0.08/1)^n

1 * (1 - 0.08)^n

1 * 0.92^n

Hence,

For nth removal,

Concentration will be :

0.92^n ; for n ≥ 1
