What volume of a 40.0 % by volume acetone solution can be
made with 20.0 mL of acetone?

50 milliliters of acetone solution

Explanation:

If a solution is 40% by volume of acetone, then we have  40 mL of acetone in a 100 mL solution. So if we have 20 mL of acetone, we get: 100 mL solution 40 mL ( CH3) 2CO⋅

20mL (CH3) 2CO  =50mL solution

answer: mercury

explanation:

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
