To make diluted solutions from concentrated solutions, we can use the following formula,
C1V1 = C2V2 
C1 is concentration and V1 is volume of concentrated solution taken to dilute the solution,
C2 is concentration and V2 is volume of diluted solution.
substituting values in the equation,
0.266 M x V = 0.075 M x 150.0 mL 
V = 23.6 mL 
therefore answer is 23.6 mL

How many grams of sucrose (c12h22o11) are in 1.55 l of 0.758 m sucrose solution? express your answer in grams to three significa
satela [25.4K]
The molecular formula of sucrose is - C₁₂H₂₂O₁₁
molecular mass of sucrose - 342 g/mol
molarity of sucrose solution is 0.758 M
In 1 L solution the number of sucrose moles are - 0.758 mol
Therefore in 1.55 L solution, sucrose moles are - 0.758 mol/L x 1.55 L
                                                                           = 1.17 mol
The mass of 1.17 mol of sucrose is - 1.17 mol x 342 g/mol = 4.00 x 10² g
