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

Determine the total pressure of a mixture of 0.400 mole of He and 0.600 mole of Ne in a 2.00 liter container at 25oC.

harina [27]

Answer:

Total pressure of the mixture is 12.2 atm

Explanation:

Let's apply the Ideal Gases law to solve this

Total pressure . V = Total moles . R . T

Total moles = 0.4 m of He and 0.6 mole of Ne → 1 mol

P . 2L = 1 mol . 0.082 L.atm/mol. K . 298K

P = ( 1 mol . 0.082 L.atm/mol. K . 298K) /2L

P = 12.2 atm
