Answer:
0.897 J/g.⁰C
Explanation:
Given the following data:
m = 170 g (mass)
ΔT = 20.0⁰C (change in temperature)
q = 3050 J (amount of heat)
The amount of heat (q) is calculated as follows:
q = m x Cp x ΔT
Thus, we introduce the data in the mathematical expression to calculate the specific heat (Cp):
Cp = q/(m x ΔT) = 3050 J/(170 g x 20.0⁰C) = 0.897 J/g.⁰C
Answer: el estudio de la síntesis, estructura, reactividad y propiedades del diverso grupo de compuestos químicos construidos principalmente de carbono
Explanation:Hope I helped:)
The density of the gas is 1.45 g/L.
The mass of the gas is 0.0707 g.
The volume of the gas is 48.9 mL.
Density = mass/volume = 0.0707 g/48.9 mL = 1.45 × 10⁻³ g/mL = 1.45 g/L
Answer : The boiling point of the resulting solution is, 
Explanation :
Formula used for Elevation in boiling point :
or,
where,
= boiling point of solution = ?
= boiling point of water = 
= boiling point constant = 
m = molality
i = Van't Hoff factor = 1 (for non-electrolyte)
= mass of solute (sucrose) = 5.0 g
= mass of solvent (water) = 10.0 g
= molar mass of solute (sucrose) = 342.3 g/mol
Now put all the given values in the above formula, we get:
Therefore, the boiling point of the resulting solution is,
