How many grams of sucrose (c12h22o11) are in 1.55 l of 0.758 m sucrose solution? express your answer in grams to three significa

satela [25.4K]

The molecular formula of sucrose is - C₁₂H₂₂O₁₁
molecular mass of sucrose - 342 g/mol
molarity of sucrose solution is 0.758 M
In 1 L solution the number of sucrose moles are - 0.758 mol
Therefore in 1.55 L solution, sucrose moles are - 0.758 mol/L x 1.55 L
= 1.17 mol
The mass of 1.17 mol of sucrose is - 1.17 mol x 342 g/mol = 4.00 x 10² g

Calculate the equilibrium constant for the reaction using the balanced chemical equation and the concentrations of the substance

Oliga [24]

Answer:

4.75 is the equilibrium constant for the reaction.

Explanation:

$CO(g)+H_2O(g)\rightleftharpoons CO_2(g)+H_2(g)$

Equilibrium concentration of reactants :

$[CO]=0.0590 M,[H_2O]=0.00600 M$

Equilibrium concentration of products:

$[CO_2]=0.0410 M,[H_2]=0.0410 M$

The expression of an equilibrium constant is given by :

$K_c=\frac{[CO_2][H_2]}{[CO][H_2O]}$

$K_c=\frac{0.0410 M\times 0.0410 M}{0.0590M\times 0.00600 M}$

$K_c=4.75$

4.75 is the equilibrium constant for the reaction.

Problem PageQuestion Methane gas and chlorine gas react to form hydrogen chloride gas and carbon tetrachloride gas. What volume

IgorC [24]

Methane gas and chlorine gas react to form hydrogen chloride gas and carbon tetrachloride gas. What volume of hydrogen chloride would be produced by this reaction if 3.16 L of chlorine were consumed at STP.

Be sure your answer has the correct number of significant digits.

Answer: Thus volume of carbon tetrachloride that would be produced is 0.788 L

Explanation:

According to ideal gas equation:

$PV=nRT$
