- What an easy recipe! I want to try it.
-
- This recipe only makes up one cake. How much of these ingredients would I need to make 3 chocolate cakes?
- INGREDIENTS:
-
- 350 g crushed chocolate cookies 370 g warm milk10 g baking powder
-
- Then she remembered a lesson she had learned in chemistry class.
- STOICHIOMETRY!!!By knowing the ratio between these ingredients, I can easily determine how much of each I should prepare.
-
-
-
- Hmm... the ratio among the ingredients is...To get the ratio of the cake I need to add up the mass of the ingredients.
-
- 350 g cookies : 370 g milk : 10 g baking powder : g cake
- 350 g cookies : 370 g milk : 10 g baking powder : 730 g cake
- 350 g + 370 g + 10 g = 730 g
-
-
- If one cake weighs 730g, then I would need to multiply it by 3 to get the weight of the three cakes. Then I would do the same to the given amount of ingredients to measure the amount of ingredients I would need to make 3 chocolate cakes.
-
- 350 g cookies : 370 g milk : 10 g baking powder : g cake
- 350 g cookies : 370 g milk : 10 g baking powder : 730 g cake
- 350 g + 370 g + 10 g = 730 g
- 730 g x 3 = 2, 190 g
- 350 g x 3 = 1, 050 g
- 370 g x 3 = 1, 110 g
- 10 g x 3 = 30 g
-
-
- And finally, the ratio of the ingredients I would need to prepare for 3 chocolates cakes is...
-
- 350 g cookies : 370 g milk : 10 g baking powder : g cake
- 350 g cookies : 370 g milk : 10 g baking powder : 730 g cake
- 1, 050 g cookies : 1, 110 g milk : 30 g baking powder : 2, 190 g cake
- 350 g + 370 g + 10 g = 730 g
- 730 g x 3 = 2, 190 g
- 350 g x 3 = 1, 050 g
- 370 g x 3 = 1, 110 g
- 10 g x 3 = 30 g
