Question

1- What mass (in g) of AgNO3 is required to make 100.0 mL of a 0.100 M solution?

2. You are preparing 2.00 L of a 1.00 M solution of hydrochloric acid. You have a stock bottle of concentrated acid (12 M). How much 12 M acid do you need to make your dilution in mL?

3-What volume (in mL) of 0.125 M AgNO3 is required to react completely with 35.31 mL of 0.225 M Na3 PO4? The balanced reaction is given below:

3 AgNO3(aq) + Nas PO4(aq) —>Ag3SO4(6)+ 3 NaNO3(aq)

4-What volume (in mL) of 0.550 M HCl is required to react completely with 4.72 g of sodium hydrogen carbonate?

NaHCO3(s)+ HCl aq) —>NaCl(aq) + CO2(g)+ H2O)

5-Determine the volume of O2 (at STP) formed when 30.0 g of KCIO3 decomposes according to the following reaction. The molar mass for KCIO3 is 122.55 g/mol.

2 KCIO3(s)—>2 KCl(s) +3 O2(g)
