What is the number of nitrogen molecules in 6.0 moles of N2?

Answers

Explanation:

just take the given moles and multiply it with the ratio of molecules to moles to get your answer

The number of nitrogen molecules in 6.0 moles of N2 is = 3.6 × 10²⁴

How to calculate number of molecules

Avogadro's number( 6.02 × 10²³) is equal to the number of molecules in 1 mole of substance.

That is,

1 mole of N2 = 6.02 × 10²³

6 moles of N2 = 6 × 6.02 × 10²³

= 36.12 × 10²³

= 3.6 × 10²⁴

Therefore, the number of nitrogen molecules in 6.0 moles of N2 is = 3.6 × 10²⁴

Write the reaction to prepare C2H5Br from (image attached)
a) alcohol using PX3
b) Alcohol using HX

Answers

The equations for the preparation of C₂H₅Br from alcohol using PX₃ and HX are shown in the attachment below.

a) Preparation of C₂H₅Br from alcohol using PX₃

In PX₃, X refers to the halides (F, Cl, Br etc.). Since the desired ethyl halide is ethyl bromide (C₂H₅Br) , then X in PX₃ will be Br. Therefore, PBr₃ will be used in the reaction as shown in the attachment below.

b) Preparation of C₂H₅Br from alcohol using HX

Also, In HX, X refers to the halides (F, Cl, Br etc.). Since the desired ethyl halide is ethyl bromide (C₂H₅Br), then X in HX will be Br. Therefore, HBr will be used in the reaction as shown in the attachment below.

Calculate the mass of a solid metal cylinder with a density of 2.6 g/cm", a
diameter of 1.8 cm, and a length of 4 cm.

Answers

Answer:

V= π ×r² × h

V = 3.14 × (0.9)² × 4

V = 3.14 × 0.81 × 4
