Answer the following:
 
Your mother gives you a bottle of orange juice concentrate to mix with water and serve it to your visiting friends. She ask you to mix two tablespoons of the concentrate with water in a glass tumbler. If each tablespoons measures 7 \(mL\) and you make  130 \(mL\) of juice per person, What is the & \(v/v\) of orange juice concentrate in the mixture you prepared ?
 
Volume of concentrate = \(2\) tablespoons
\(1\) tablespoon =  7
So, volume of concentrate = \(mL\) 
Total volume of solution = \(mL\)
 
Volume by volume percentage \(v\) / \(v\) \(\%\) = ) \(\times 100\).
 
The volume by volume percentage \(=\)  \(\%\)
