A recipe calls for 1 cup of milk and 4 eggs. If you only have 2 eggs, how much milk should you use?
-
1 cup
-
2 cups
-
1/2 cup
-
4 cups
Correct Answer
A. 1/2 cupExplanation
If the recipe calls for 4 eggs and you only have 2 eggs, it means you have half of the required amount of eggs. Therefore, it would make sense to also use half of the required amount of milk, which is 1 cup. Hence, the correct answer is 1/2 cup.Rate this question:

A recipe calls for one cup of milk and 4 eggs. If you want to triple the recipe, how many eggs do you need?
-
3 cups
-
12 eggs
-
12 cups
-
3 eggs
Correct Answer
A. 12 eggsExplanation
If the recipe calls for one cup of milk and 4 eggs, and we want to triple the recipe, we need to multiply the number of eggs by 3. Therefore, 4 eggs multiplied by 3 equals 12 eggs. So, if we want to triple the recipe, we will need 12 eggs.Rate this question:

A bicycle mechanic has 10 frames and 16 wheels in the shop. How many complete bicycles can he assemble using these parts?
-
2
-
4
-
6
-
8
-
10
Correct Answer
A. 8Explanation
The bicycle mechanic can assemble 8 complete bicycles using the 10 frames and 16 wheels in the shop. Each bicycle requires 1 frame and 2 wheels. Since there are only 10 frames available, the mechanic can assemble a maximum of 10 bicycles. However, since each bicycle requires 2 wheels, a total of 20 wheels would be needed for all 10 bicycles. Since there are only 16 wheels available, the mechanic can only assemble 8 complete bicycles.Rate this question:

What is the molar mass of CH4?
-
12 g/mol
-
24g/mol
-
20 g/mol
-
16 g/mol
-
None of the above
Correct Answer
A. 16 g/molExplanation
The molar mass of CH4 is 16 g/mol because carbon has a molar mass of 12 g/mol and hydrogen has a molar mass of 1 g/mol. Since there are four hydrogen atoms in CH4, the total molar mass is 12 g/mol + 4 g/mol = 16 g/mol.Rate this question:
