# moles = mass (g) / Mr (relative atomic mass)
# moles = 458 / ((23*2)+32+(16*4)
# moles= 458 / 142 = 3.2253521126760...
= 3.23 moles
Answer:
3 pieces of lunch-meat and 2 slices of cheese
Explanation:
You have enough bread to make 3 sandwiches
You have enough lunch-meat to make 4 sandwiches
You have enough cheese to make 5 sandwiches
In all you have enough material to make 3 sandwiches
so if you subtract three from each number above you will have no bread, enough lunch-meat to make one sandwich and enough cheese to make two sandwiches
luch-meat for one sandwich is: 3 pieces
Cheese for two sandwiches is: 2 pieces
The element iron is malleable and conducts electricity.
Answer: (1) iron
- Glucose = C₆H₁₂O₆.
- Atomic mass of C = 12 u
- Atomic mass of H = 1 u
- Atomic mass of O = 16 u
- Therefore, the molecular mass of glucose
- = (6 × Atomic mass of C) + (12 × Atomic mass of H) + (6 × Atomic mass of O)
- = (6 × 12) + (12 × 1) + (6 × 16) u
- = 72 + 12 + 96 u
- = 180 u

the ocean is closely tied to human health so there is higher demand for fisheries to supply many sea life organisms for food and may directly be a cause in the drop sea life population over the years. this also raises the price of the dish because supply doesn't meet demand
