Answer:
1. 315.4 K
2. 1560 °C
Explanation:
To convert from celsius to Kelvin, the following formula can be used:
T(K) = T(°C) + 273
Where:
T(K) => Temperature in Kelvin
T(°C) => Temperature in degree celsius
1. Determination of the temperature in Kelvin.
Temperature (T) in °C = 42.4 °C.
Temperature (T) in K =?
T(K) = T(°C) + 273
T(K) = 42.4 °C + 273
T(K) = 315.4 K
2. Determination of the temperature in degree Celsius.
Temperature (T) in K = 1833 K
Temperature (T) in °C =?
T(K) = T(°C) + 273
1833 = T(°C) + 273
Collect like terms
T(°C) = 1833 – 273
T(°C) = 1560 °C
Answer:
6%
Explanation:
Hello, for this case, we assume that the volume of the solution is 1L, thus, the mass is given by using the density as follows:

Now, the mass of the ethanol:

Finally, the by mass percent is:
