Answer:
2/5 cups of silver oxide
1/10 cups of water
1/10 cups of potassium
Explanation:
5+ 5 + 10 + 10+ 20 = 50
there are 50 total cups
now we must find the number to divide 50 by to get the 1 cup that we need
50 / 50 = 1
Now that we know what to divide by to get the quantities for 1 cup of solution, time to get the quantities
there are 20 cups of Silver oxide
20 / 50 = 2/5 cups
there are 5 cups of water
5 / 50 = 1/10 cups
there are 5 cups of potassium
5 / 50 = 1/10 cups
