<span>The relationship between the number of carbon atoms and boiling point is inversely proportional. In the alkane series of hydrocarbons, as the number of carbon atoms decreases, the normal boiling point of the compounds decreases. The reason behind this is that longer chains of molecules require more energy to separate the bonds while shorter chains or molecules with lower number of carbon atoms require less energy to break away from each other. Thus, low carbon molecules have lower boiling point.</span>
Answer:
124 g (3 sig figs)
or
124.011 g (6 sig figs
Explanation:
Step 1: Calculate g/mol for AgNO₃
Ag - 107.868 g/mol
N - 14.01 g/mol
O - 16.00 g/mol
107.868 + 14.01 + 16.00(3) = 169.878 g/mol
Step 2: Multiply 0.73 moles by molar mass
0.73 mol (169.979 g/mol)
124 grams of AgNO₃
Density of an object is computed by dividing its mass by its volume. D = M / V
Solution:
D = 500 g / 2.75 cm3
D = 181.82 g/cm3
Further, density of an object is computed by dividing its mass by its volume. D = M / V
However, since Volume is the missing component in the equation. Mass of an object is divided by its density to get its volume. V = M / D
<span>Volume of Gold nugget = 50 g </span>/<span> 19.3g/cm3 = </span>2.59cm3
<span>Volume of Iron Pyrite nugget = 50 g </span>/ <span>5.0g/cm3 = </span>10cm3
