What volume of ethanol in mL is found in a 750 ml bottle of 40% (v/v) vodka (80 proof)? a. 0.300 ml b. 3.00mL c. 30.0 mL d. 300 ml

Answer 1

1.That occurs when the level of sodium in the blood is too low.

a. Consuming an excess of water.

This dilute the concentration of sodium.

2.concentration is amount of solute in specific volume of solution.

3) quantity of solute can be measured in any of the above method

4) volume of cube =10*10*10 cm3

=1000ml as 1cm3=1ml

And 1000ml =1 liter hence 1 liter is the answer
