1. Calculate the number of grams of citric acid, C6H8O7, needed to make 2500mL of 0.4 M C6H8O7.
2. How many grams of sodium hydroxide, NaOH, would you have to dissolve in 250 mL of water to make a 0.5 M solution of NaOH?
3. How many liters of water are required to make a 0.2M solution sulfide, Na2S, using 200g of Na2S?© BrainMass Inc. brainmass.com December 19, 2018, 9:24 pm ad1c9bdddf
1. In this question, you need to be able to apply the formula:
where molarity is in M
Mole is in mol
Volume is in L
First, the molecular weight of C6H8O7=6*12+8+16*7=192(g/mol)
The solution provides detailed calculations and explanations for the problem.
