Answer:
79.89%
Explanation:
Copper has a molar mass of 63.55
Oxygen has a molar mass of 16.00

Answer:
25 grams (25g) of sugar
Explanation:
We can set this up algebraically:
10g = 2L
÷ 2 ÷ 2
5g = L
meaning that 5 g are needed to make 1 L
So, if we have 5 L, we will need (5 × 5) 25 grams to produce the same concentration.
