Answer 1

Answer:

As Per Given Information

Given mass of H₂O₂ ( Hydrogen Peroxide) 4.0 gm

We've been asked to find the number of moles in Hydrogen Peroxide .

First we calculate molecular mass of Hydrogen Peroxide .

Molecular mass of H₂O₂ = 1×2 + 16 × 2

Molecular mass of H₂O₂ = 2 + 32

Molecular mass of H₂O₂ = 34 gm

Now find the number of moles in given hydrogen peroxide .

[tex] \diamond{\boxed{\blue{\bf{Number \: of \: moles \: = \frac{Given \: mass}{Molecular \: mass} }}}} [/tex]

Put the given value we obtain

[tex] \sf \twoheadrightarrow \: Number \: of \: moles \: = \frac{4}{34} \\ \\ \sf \twoheadrightarrow \: Number \: of \: moles \: =0.117[/tex]

So, the number of moles is 0.117 .

Answer 2

Molar mass of Hydrogen peroxide

2(1)+2(16)34g/mol

No of moles

Given mass/Molar mass4/340.117mol

What is the number of molecules of CO2 in 0.236 moles?

Answers

Answer:

mole of CO2 = 6.023*10^23 molecules.

3 moles of CO2 = 3*6.023*10^23 molecules

therefore, 3 moles of CO2 = 18069*10^20 molecules.

c. 2.5 % 1023 molecules
_____ mol​

Answers

Answer:

1.520

1.333

15.899

Explanation:

its very easy

N = n x No

No = avogadro's number = 6.02 x 10²³

n = mol

a. 9.52 x 10²⁶ : 6.02 x 10²³ = 1.58 x 10³ (3 sig figs)

b. 7.81 x 10²² : 6.02 x 10²³ = 1.30 x 10⁻¹ = 0.130 (3 sig figs)

c. 2.5 x 10²³ : 6.02 x 10²³ = 0.42 (2 sig figs)
