This element would have 122 neutrons.

Atomic mass is the accumulation of neutrons and protons.

169 - 47 = 122.

Therefore, there are 122 neutrons.

erastovalidia [21]

Answer:

We'll have 13.85 grams of potassium

Explanation:

Step 1: Data given

Moles KBr = 0.46 mol

Molar mass KBr = 119.00 g/mol

Molar mass K = 30.10 g/mol

Step 2: The balanced equation

2KBr ⇆ 2K + Br2

Step 3: Calculate moles of K

For 2 moles KBr consumed we'll have 2 moles K and 1 mol Br2

For 0.46 moles KBr we'll have 0.46 moles K

Step 4: Calculate mass of K

Mass K = moles K * molar mass K

Mass K = 0.46 moles * 30.10 g/mol

Mass K = 13.85 grams

We'll have 13.85 grams of potassium

What is the partial pressure of carbon monoxide gas in a sealed vessel that has a total pressure of 2.68 atm and partial pressur
Alika [10]
Pt = p1 + p2 + p3, p1 = pp (CO) atm
2.68 atm = p1 + 1.56 atm + 0.65 atm
2.68 = p1 + 2.21
p1 = 2.68 - 2.21
p1 = 0.47 atm
