If a dog has a mass of 16.1 kg, what is its mass in the following units? Use scientific notation in all of your answers.

nekit [7.7K]

Answer:

$16.1\times 10^3\ \text{g}$

$16.1\times 10^{6}\ \text{mg}$

$16.1\times 10^{9}\ \mu\text{g}$

Explanation:

Mass of dog = $16.1\ \text{kg}$

$1\ \text{kg}=10^{3}\ \text{g}$

$1\ \text{kg}=10^{6}\ \text{mg}$

$1\ \text{kg}=10^{9}\ \mu\text{g}$

So,

$16.1\ \text{kg}=16.1\times 10^3\ \text{g}$

$16.1\ \text{kg}=16.1\times 10^{6}\ \text{mg}$

$16.1\ \text{kg}=16.1\times 10^{9}\ \mu\text{g}$

Mass of the dog in the other units is $16.1\times 10^3\ \text{g}$ , $16.1\times 10^{6}\ \text{mg}$ and $16.1\times 10^{9}\ \mu\text{g}$ .

An aerosol can with a temperature of 292 K and a pressure of 1.25 atm was left outside in the sun on a hot summer day. The press

garik1379 [7]

Answer:

310.69K

Explanation:

Given parameters:

Initial temperature T₁ = 292K

Initial pressure P₁ = 1.25atm

Final pressure P₂ = 1.33atm

Unknown:

Final temperature T₂ = ?

Solution

To find the unkown, we need to apply the combined gas law. From the combined gas law, it can be deduced that at constant volume, the pressure of a give mass or mole of gas varies directly with the absolute temperature.

Since the same aerosol can is heated, the volume is constant.

$\frac{P_{1} }{T_{1} }$ = $\frac{P_{2} }{T_{2} }$

Now, we have to make T₂ the subject of the formula:

T₂ = $\frac{P_{2} x T_{1} }{P_{1} }$

T₂ = $\frac{1.33 x 292 }{1.25 }$ = 310.69K
