Determine the pH of a solution that is 1.75% NaOH by mass. Assume that the solution has density of 1.01 g/mL.
How many grams of H3PO4 are in 175 mL of a 3.5 M solution of H3PO4?
How many grams of NO(g) can be formed from 3.0 moles of NH3(g) if there is sufficient O2(g) to use all of the ammonia?
A solution is prepared by mixing 75.0 mL of 5.00 M HCl and 20.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+], [OH -], and the pH for this solution.
calculate the moles of CO2 you would theoretically expect from 0.253 grams of an alka-seltzer tablet at 721. torr and 291. K.
