To determine whether the crown was made of pure gold or not, we need to compare the density of gold (19.3 g/mL) to the density of the crown.

The formula for density is

$Density=\frac{mass}{volume}$

we know the mass of the crown is 714 grams and its volume is 38.3 mL. (Because it displaces 38.3 mL of water)

Using this information, we can plug the numbers into our density formula to solve for the density of the crown.

$\frac{714 grams}{38.3 mL} = 18.6 g/mL$

The density of the crown is 18.6 g/mL, thus the crown was not made of pure gold, as that has a density of 19.3 g/mL. In conclusion, the goldsmith tried to screw over the king.

The formula weight of potassium dichromate (k2cr2o7) is __________ amu.

Gre4nikov [31]

The given compound is $K_{2}Cr_{2}O_{7}$

Each formula unit of $K_{2}Cr_{2}O_{7}$ has 2 mol Potassium (K) atoms, 2 mol Chromium (Cr) atoms and 7 mol Oxygen (O) atoms.

Atomic weight of potassium is 39.0983 amu

Atomic weight of Chromium is 51.9961 amu

Atomic weight of Oxygen is 15.9994 amu.

Therefore the formula weight of $K_{2}Cr_{2}O_{7} =$

$2 * 39.0983 amu + 2 * 51.9961 amu + 7 * 15.9994 amu$

= 294.1846 amu

11mg of cyanide per kilogram of body weight is lethal for 50% of domestic chickens. How many grams per kilogram of body weight i

Nookie1986 [14]

Answer:

$0.033g$

Explanation:

Hello,

In this case, since 11 mg per kilogram of body weight has the given lethality, the mg that turn out lethal for a chicken weighting 3 kg is computed by using a rule of three:

$11mg\longrightarrow 1kg\\\\x\ \ \ \ \ \ \longrightarrow 3kg$

Thus, we obtain:

$x=\frac{3kg*11mg}{1kg}\\ \\x=33mg$

That in grams is:

$=33mg*\frac{1g}{1000mg} \\\\=0.033g$

Regards.
