How many moles of nitrogen are there in a 16,500 mL sample of nitrogen at STP?

Chemistry
1 answer:
GalinKa [24]3 years ago
4 0

Answer : The number of moles of nitrogen present are, 0.737 mol

Explanation :

As we know that at STP, 1 mole of substance occupies 22.4 L volume of gas.

As per question,

As, 22.4 L volume of nitrogen gas present in 1 mole of nitrogen gas

Conversion used : 1 L = 1000 mL

Or, 22400 mL volume of nitrogen gas present in 1 mole of nitrogen gas

So, 16500 mL volume of nitrogen gas present in \frac{16500}{22400}=0.737 mole of nitrogen gas

Therefore, the number of moles of nitrogen present are, 0.737 mol

average atomic mass of Cu = 63.54

Explanation:

average atomic mass =  atomic mass of isotope 1 × abundance of isotope 1 + atomic mass of isotope 2 × abundance of isotope 2 +...+ atomic mass of isotope n × abundance of isotope n

average atomic mass of Cu = atomic mass of Cu-63 × abundance of isotope Cu-63 + atomic mass of isotope Cu-65 × abundance of isotope Cu-65

average atomic mass of Cu = 62.93 × (69.17 / 100) + 64.93 × (30.83 / 100)

average atomic mass of Cu = 63.54

Answer:

See Explanation

Explanation:

10) From the options provided for this question, gamma particle is the most energetic. Recall that gamma rays are high energy electromagnetic radiation which are capable of causing a high degree of ionization in matter.

11) The bombardment of U-235 with neutrons leads to the reaction;

U\frac{235}{92}  + n\frac{1}{0}---> I\frac{138}{53}  + Y\frac{95}{39} +3n \frac{1}{0}

Hence

a = 92, b= 95, c= 53

12) In positron emission, a proton is transformed into a neutron. The mass number of the daughter nucleus is the same as its parent but the atomic number decreases by 1.

Hence;

Th\frac{231}{90} -----> e\frac{1}{0} +Ac \frac{231}{89}
