How many grams are in 4.23E44 particles of PbO2
ASHA 777 [7]

1.679 × 10²³ g of PbO₂ is present in 4.23×10⁴⁴ particles of PbO₂.

<u>Explanation:</u>

First the number of particles is converted into moles by dividing it by the Avogadro's number and then moles multiplied by the molar mass, we will get the mass of PbO₂ in grams.

4.23×10⁴⁴/ 6.022×10²³ = 7.02×10²⁰ moles

Now we have to multiply this by the molar mass of PbO₂, that is 239.2 g/mol, we will get the mass in grams.

7.02×10²⁰ moles × 239.2 g/mol = 1.679 × 10²³ g of PbO₂

 Convert the following to moles.
Luda [366]
Use dimensional analysis.
\frac{60.0 grams NaOH}{1} *  \frac{1 mole NaOH}{40.0 amu NaOH} =1.5 moles

\frac{2.73 grams NH4Cl}{1} *  \frac{1 mole NH4Cl}{53.49 amu NH4Cl} = .051 moles

Now you try converting moles to grams. All you have to do is start with MOLES  (Unlike the previous examples) over 1 then multiply that ratio by the ratio of molar mass over 1 mole. Hope this helps!

If 10 grams of NaHCO3 react with an excess of HCl, what would be the theoretical mass of NaCl produced?
melamori03 [73]

Answer:

Explanation:Reaction NaHCO3 + HCl ⇒ NaCl + H2O + CO2

Molar mass M = (22.99+1.008+ 12.01+3·16 ) g/mol. Calculate

Amount of substance n =m/M, n(NaCl) is equal.

M(NaCl) = 58.44 g/mol and mass m= n·M
