Calculate the mass of 4.55x1024 molecules of sucrose

Chemistry

Answer:

2584 g

Explanation:

The molecular formula for sucrose is C₁₂H₂₂O₁₁, which means its molar mass is 342.3 g/mol.

First we<u> convert molecules into moles</u> by using <em>Avogadro's number</em>:

  • 4.55x10²⁴ molecules ÷ 6.023x10²³ mol/molecules = 7.55 mol

Now we <u>convert moles of sucrose into grams</u>, using its<em> molar mass</em>:

  • 7.55 mol * 342.3 g/mol = 2584 g

olganol [36]
When highly electronegative element like oxygen is directly attached to less electronegative element like hydrogen the electrons from less electronegative elements are attracted toward the highly electronegative element, making the less electronegative element deficient in electron density (partial positive) and a partial negative charge on more electronegative element is created. In such situation the intermolecular forces formed are dipole-dipole interactions or hydrogen bond interaction like in HF.

One mole of neon, a monatomic gas, starts out at conditions of standard temperature and pressure. the gas is heated at constant
Anna71 [15]
<span>We can use the ideal gas law PV=nRT For the first phase The starting temperature (T1) is 273.15K (0C). n is 1 mole, R is a constant, P = 1 atm, V1 is unknown. The end temperature (T2) is unknown, n= 1 mol, R is a constant, P = 3*P1= 3 atm, V2=V1 Since n, R, and V will be constant between the two conditions: P1/T1=P2/T2 or T2= (P2*T1)/(P1) so T2= (3 atm*273.15K)/(1 atm)= 3*273.15= 816.45K For the second phase: Only the temperature and volume change while n, P, and R are constant between the start and finish. So: V1/T1=V2/T2 While we don't know the initial volume, we know that V2=2*V1 and T1=816.45K So T2=(V2*T1)/V1= (2*V1*T1)/V1=2*T1= 2*816.45K= 1638.9K To find the total heat added to the gas you need to subtract the original amount of heat so 1638.9K-273.15K= 1365.75K</span>
