A sample of 18.11 grams of sodium hydroxide is weighed out on a balance and prepared to a volume of 2.00 x 102 mL in water. What is the molarity of this aqueous solution of NaOH?
Express your answer to the correct number of significant figures and include the unit with your answer.
Dimensional Analysis is a way of doing numerical "book-keeping"
when converting quantities or performing calculations.
• When converting quantities from one unit to another,
conversion factors are used.
Solving with Dimensional Analysis and Multiple Units:
If I am in Canada where the price of gas is $1.022 USD·L1, how
much will it cost me to fill up my gas tank if I travelled 125 km?
• Let's also assume that my car gets
an average of 30.0 miles/gallon.

- A 124-g sample of a pure liquid, liquid A, with a density of 3.00 g/mL is mixed with a 40.8-mL sample of a pure liquid, liquid B, with a density of 2.00 g/mL. What is the total volume of the mixture? (Assume there is no reaction upon the mixing of A and B, and volumes are additive.)arrow_forwardOn October 21, 1982, the Bureau of the Mint changed the composition of pennies (see Exercise 120). Instead of an alloy of 95% Cu and 5% Zn by mass, a core of 99.2% Zn and 0.8% Cu with a thin shell of copper was adopted. The overall composition of the new penny was 97.6% Zn and 2.4% Cu by mass. Does this account for the difference in mass among die pennies in Exercise 120? Assume the volume of the individual metals that make up each penny can be added together to give the overall volume of the penny, and assume each penny is the same size.
