If a solution has concentration 35.2 g/dm3 and you take 25.0 cm3 of it, how many grams of solute are in that 25.0 cm3?
Which calculation gives the number of moles of gas in 24.0 dm3 at RTP?
A solution contains 35.2 g/dm3 NaCl. If sodium is 39.3% by mass of NaCl, what is the mass concentration of sodium ions in g/dm3?

How many moles of gas are present in 150 cm3 at room temperature and pressure?
25.00 cm3 of hydrochloric acid is titrated with 23.50 cm3 of 0.100 mol/dm3 barium hydroxide. The reaction is 2HCl + Ba(OH)2 ? BaCl2 + 2H2O. What is the concentration of HCl?
What is the molar volume (dm3) of 0.250 mol of gas at room temperature and pressure (1 mol = 24 dm3)?
What is the number of moles in 25.0 cm3 of a 0.100 mol/dm3 solution?
A mean value is written as 16.5 ± 0.3 °C. What does “± 0.3 °C” most correctly represent?
What volume (in dm3) of any gas at room temperature and pressure is produced by 0.500 mol of the gas? (Use 1 mol = 24 dm3)
