Answer:

70 [milliliters]

Explanation:

Since the solution consists of 90% alcohol, the 63 milliliters of alcohol must represent 90% of the entire solution. Let the solution have
x milliliters in total. We have the following equation:


0.9x=63

Divide both sides by 0.9:


x=(63)/(0.9)=\boxed{70}

Therefore, there are 70 milliliters in the solution.
