Answer:
Molecular formula = C₆H₁₂O₆
Explanation:
Given data:
Mass of hydrogen = 31.7 g
Mass of carbon = 283.4 g
Mass of oxygen = 377.4 g
Molar mass of compound = 176.124 g/mol
Molecular formula = ?
Solution:
Number of gram atoms of H = 31.7 / 1.01 = 31.4
Number of gram atoms of O = 377.4 / 16 = 23.6
Number of gram atoms of C = 283.4 / 12 = 23.6
Atomic ratio:
C : H : O
23.6/23.6 : 31.4/23.6 : 23.6/23.6
1 : 1.33 : 1
C : H : O =3 (1 : 1.33 : 1
)
Empirical formula is C₃H₄O₃.
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass = 3×12+4+3×16 = 88
n = 176.124 / 88
n = 12
Molecular formula = n (empirical formula)
Molecular formula = 2 (C₃H₄O₃)
Molecular formula = C₆H₁₂O₆

Explanation:
In the given question, Its basic understanding to also be hired seems to be that coffee heat = heat that the milk absorbs
The following relationship defines heat:

Its updated equation is:

The following information is provided to you as per the question:
1) Milk and coffee have the same heat power
2) Difference in coffee temperature is:

3) The difference in milk temperature:


4) Milk and coffee density are equal therefore, weight and volume are equal and have same ratio, that can be shown as follows:


by replace the equation values (b) for calculating milk volumes as shown as follows:


Answer:the other ball hits the ground

Explanation:
V1 = 445ml V2 = 499ml
T1 = 274 K T2 = ?
By Charles Law,
V1/T1 = V2/T2
445/274 = 499/T2
By solving we get,
T2 = 307.25 K
