Answer:
No, it doesn't.
Explanation:
To convert ppb to mg/m³ we first need to convert to ppm, by just divide the amount by 1,000, so the concentration in the sample is 4.8 ppm.
mg/m³ = (ppm x molar mass)/molar volume
Using the molar mass in gram and the molar volume in liters, multiplying by the parts per million, we will get the concentration in mg/m³.
Molar mass of C = 12 g/mol; molar mass of Cl = 35.5 g/mol
Molar mass of CCl4 = 12 + 4x35.5 = 154 g/mol
Assuming, 25ºC and 1 atm, the molar volume of an ideal gas is 24.45 L, so:
mg/m³ = (4.8 x 154)/24.45
mg/m³ = 30.2
Which is higher than the limit of 12.6 mg/m³

Answer:
C3H3O
Explanation:
Now, what we need to do is to divide the percentage compositions by the relative atomic masses.
The relative atomic mass of carbon 12, the relative atomic mass of hydrogen is 1 while the atomic mass of oxygen is 16.
We now do the divisions as follows:
Carbon = 63.15/12 = 5.2625
Oxygen = 31.55/16 = 1.971875
Hydrogen = 5.30/1 = 5.30
Now,we now divide by the smallest I.e that of oxygen.
Carbon = 5.2625/1.971875 = 2.668
Oxygen = 1.971875/1.971875 = 1
Hydrogen = 5.3/1.971875= 2.688
We can round up the ratio of carbon and hydrogen to 3.
Thus, the empirical formula is C3H3O
A:The half-life should be similar to the age of the object.
