Explanation:
getting the empirical formula
For carbon
3.01/12 = 0.2508
For oxygen
4/16 = 0.25
For Cl
17.81/35.5= 0.501
0.2508 ÷ 0.25 = 1.0032
0.25 ÷ 0.25 = 1
0.501 ÷ 0.25 = 2.004
Empirical formula of the compound = CCl20
Molar mass = (1×12) + (2×35.5) + (1×16)
= 12 + 71 + 16
= 99g/mol
percentage composition= 24.81/99 × 100
= 25.06%
Answer:
119.5 J
Explanation:
First we <u>calculate the temperature difference</u>:
- ΔT = 100 °C - 50 °C = 50 °C
Then we can <u>calculate the heat released</u> by using the following formula:
Where q is the heat, Cp is the specific heat, ΔT is the temperature difference and m is the mass.
We <u>input the data</u>:
- q = 0.239 J/g°C * 50 °C * 10.0 g
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can be later released to fuel the organisms activities.
The molality of the solution is 1.4 moles per kilogram (molal).
The molality of the solution is equal to the number of moles of sugar (solute) divided by the number of kilograms of water (solvent). Hence, the molality is determined below:
The molality of the solution is 1.4 moles per kilogram (molal).
