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 .

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

Put the given value we obtain

\sf \twoheadrightarrow \: Number \: of \: moles \:  =  \frac{4}{34}  \\  \\ \sf \twoheadrightarrow \: Number \: of \: moles \:  =0.117

So, the number of moles is 0.117 .

Yasmin's teacher asks her to make a supersaturated saline solution. Her teacher tells her that the solubility of the salt is 360
Aleks [24]

Answer:

She can add 380 g of salt to 1 L of hot water (75 °C) and stir until all the salt dissolves. Then, she can carefully cool the solution to room temperature.  

Explanation:

A supersaturated solution contains more salt than it can normally hold at a given temperature.

A saturated solution at 25 °C contains 360 g of salt per litre, and water at 70 °C can hold more salt.

Yasmin can dissolve 380 g of salt in 1 L of water at 70 °C. Then she can carefully cool the solution to 25 °C, and she will have a supersaturated solution.

B and D are wrong. The most salt that will dissolve at 25 °C is 360 g. She will have a saturated solution.

C is wrong. Only 356 g of salt will dissolve at 5 °C, so that's what Yasmin will have in her solution at 25 °C. She will have a dilute solution.
