Question

1.) Given 30 grams of CO2, how many moles of CO2 would you have? How many individual molecules of CO2 is that?
2., Given 22 Grams of NaCl, How many moles of Nacl would you have? How many individual molecules of NaCl is that?
3.) Given 50 grams of ammonia NH3, How many moles of NH3 would you have? How many Molecules of NH3 is that?​

Answer 1

Answer:

1a) .68 moles 1b)4.1E-23 molecules.

2a) .37 moles 2b) 2.27E-23 molecules

Explanation:

1a) CO2 is equal to 44 grams (C→12 grams,O→16 grams[·2]) .30g/44g is .68 moles.

1b) multiply 1A by advogadros number (6.022E-23)

2a) NaCl is 58 grams. 22/58 is .37 moles.

2b) multiply 2A by advogadros number.

you'd answer #3 the same way #1 and #2

Answer 2

The branch of science that deals with chemicals and bonds are called chemistry. The moles are units to calculate the quantity required to use the element.

The correct answer is mentioned below.

What are moles?

• The mole is the base unit of the amount of substance in the International System of Units (SI).
• It is defined as exactly 6.02214076×10^23 elementary entities which may be atoms, molecules, ions, or electrons.

According to the question, the moles to the option is as follows:-

1. moles of 30 grams of CO2 is

$n =\frac{M}{M.M}\\ \\\frac{30}{44} \\\\=0.681$

The number of molecules is $0.68 *6022*10^{23} =4.09496*10^{23$.

2. moles of 22 grams of NaCl is

$\frac{22}{44}\\ \\=0.5$

Molecules will be $0.5*6.022*10^{23} = 3.011*10^{23}$

3. moles of 50-gram ammonia

$\frac{50}{17} \\\\2.94$

The number of molecules is $2.94*6.022*10^{23} = 1770*10^{23$
