Which of the following are needed to calculate the percent yield? Select all that apply. Question 10 options: Theoretical yield
Ivahew [28]

Both theoretical and actual yields would be needed to calculate percent yield.

The percent yield of a reaction is defined as the ratio of the actual yield to that of the theoretical yield. It can be mathematically expressed as:

percent yield = actual yield/theoretical yield x 100%

The actual yield is the amount of a specific product produced from a reaction while the theoretical yield is the stoichiometric amount of the same product.

A recipe for bread states that the dough must bake for 40 minutes at a temperature of 190°C. The oven you are using has temperat
Mila [183]

Answer:

374°F

463.15K

Explanation:

This particular Question wants to test knowledge on the conversion of the units of temperature from celsius degree to degree Fahrenheit. Also, the conversion of degree celsius to kelvin.

The value given which is 190 degree celsius can be converted into degree Fahrenheit using the formula below;

(x°C × 9/5 ) + 32.

Therefore, x = 190°C =( 190°°C × 9/5) + 32 = 374°F.

The conversion of degree celsius to kelvin is given below as;

x°C + 273.15 .

Therefore, x = 190°C = 190°C + 273.15 = 463.15K.

Therefore, the temperature needed to bake at Fahrenheit and kelvin are 374°F and 463.15K respectively.
