Answer: The volume of solution is 0.0459 L

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution

Molarity=\frac{n}{V_s}

where,

n = moles of solute

V_s = volume of solution in L

moles of HCl (solute) = \frac{\text {given mass}}{\text {Molar mass}}=\frac{2.43g}{36.5g/mol}=0.0666

Now put all the given values in the formula of molality, we get

1.45M=\frac{0.0666}{V_s}

V_s=\frac{0.0666}{1.45}=0.0459

Therefore, the volume of solution is 0.0459 L

the chemical formula of potassium dichromate is K2Cr2O7.state the ratio of potassium, chromium and oxygen atom in the compounds
Len [333]

Answer:

Potassium Dichromate is an orange to red colored, crystalline, inorganic compound that emits toxic chromium fumes upon heating. Potassium dichromate is highly corrosive and is a strong oxidizing agent. This substance is used in wood preservatives, in the manufacture of pigments and in photomechanical processes, but is mainly replaced by sodium dichromate. Potassium dichromate primarily affects the respiratory tract causing ulcerations, shortness of breath, bronchitis, pneumonia and asthma but can also affect the gastrointestinal tract, liver, kidneys and immune system. This substance is a known human carcinogen and is associated with an increased risk of developing lung cancer and cancer of the sinonasal cavity. (NCI05)
