Elena-2011 [213]3 years ago
3 0

Answer: Ag:  2.79x10^22 atoms

              C atoms:  6.02x10^23 C atoms

Explanation:

5.0 grams of Ag is 0.0464 moles of Ag.  (0.0464 moles)*(6.02x10^23 atoms/mole) = 2.79x10^22 atoms Ag

(0.50 moles)*(6.02x10^23 molecules/mole)*(2 C atoms/molecule) = 6.02x10^23 atoms of C

If 5.4 g of NaNO3 is dissolved in 350 mL of water, what is the molarity of the solution?
Aleonysh [2.5K]

Answer:

0.18 Moles

Explanation:

first you need to convert the 5.4g to moles using molar mass

(\frac{5.4g}{1})(\frac{1mol}{84.99g} )=\frac{5.4g}{84.99g} =0.0635mol NaNO_{3})

once you have that done you can use the molarity equation to get the answer

M=\frac{0.0635mol}{0.350ml} =0.181428

now you need to round to the correct sig fig which will give you the correct answer of 0.18moles
