2 answers:

8 0

Answer:

Aroma are bigger than protons.
Protons are smaller than atoms.

Explanation:

Inside a nucleus are neutrons and protons, which occupy a space about 100,000 times smaller than the whole atom.

A hydrogen atom is 100,000 times bigger than the proton that sits in the middle of it!

PLEASE HELP!!!!!!!!! WILL MARK BRAINLIEST

frozen [14]

Answer:

19.278049929737628457607385688801

Explanation:

Volume = L * W * H

Volume = 17.78 * 9.21 * 4.45 = 728.70441

Density = Mass / Volume

Mass = 14,048

14,048 / 728.70441 = 19.278049929737628457607385688801

Density = 19.278049929737628457607385688801

An unknown compound with a molar mass of 223.94 g/mol consists of 32.18% c, 4.50% h, and 63.32% cl. find the molecular formula f

Dima020 [189]

The actual number of atoms of each element present in the molecule of the compound is represented by the formula known as molecular formula.

Molar mass of the unknown compound = 223.94 g/mol (given)

Mass of each element present in the unknown compound is determined as:

Mass of carbon, $C$ :

$\frac{32.18}{100}\times 223.94 = 72.06 g$

Mass of hydrogen, $H$ :

$\frac{4.5}{100}\times 223.94 = 10.08 g$

Mass of chlorine, $Cl$ :

$\frac{63.32}{100}\times 223.94 = 141.79 g$

Now, the number of each element in the unknown compound is determined by the formula:

$number of moles = \frac{given mass}{molar mass}$

Number of moles of $C$ :

$number of moles = \frac{72.06}{12} = 6.005 mole\simeq 6 mole$

Number of moles of $H$ :

$number of moles = \frac{10.08}{1} = 10.08 mole\simeq 10 mole$

Number of moles of $Cl$

$number of moles = \frac{141.79}{35.5} = 3.99 mole\simeq 4 mole$

Dividing each mole with the smallest number of mole, to determine the empirical formula:

$C_{\frac{6}{4}}H_{\frac{10}{4}}Cl_{\frac{10}{4}}$

$C_{1.5}H_{2.5}Cl_{1}$

Multiplying with 2 to convert the numbers in formula into a whole number:

So, the empirical formula is $C_{3}H_{5}Cl_{2}$ .

Empirical mass = $12\times 3+1\times 5+2\times 35.5 = 112 g/mol$

In order to determine the molecular formula:

n = $\frac{molar mass}{empirical mass}$

n = $\frac{223.94}{112} = 1.99 \simeq 2$

So, the molecular formula is:

$2\times C_{3}H_{5}Cl_{2} = C_{6}H_{10}Cl_{4}$

A dose of aspirin of 5.0 mg per kilogram of body weight has been prescribed to reduce the fever of an infant weighing 8.5 pounds

Tanya [424]

<h3><u>Answer</u>;</h3>

19 mg

<h3><u>Explanation</u>;</h3>

dose = 5.0 mg/kg

weight of infant = 8.5 pounds

Convert 8.5 pounds to kg: 8.5 pounds = 3.86 kg

Therefore;

The dose to give the infant is:

= (5.0 mg/kg) x (3.86 kg)

= 19.3 mg

<u>≈ 19 mg</u>
