What mass of oxalic acid dihydrate, H2C2O4•2H2O, is needed to make a 0.357 M solution of oxalic acid in a 250.0mL volumetric fla
GalinKa [24]

Molarity is expressed as the number of moles of solute per volume of the solution. The mass of oxalic acid dihydrate needed for the solution is calculated as follows:

Amount in moles: (0.357 mol H2C2O4•2H2O / L) (.250 L ) = 0.0893 mol H2C2O4•2H2O


Amount in mass : 0.0893 mol H2C2O4•2H2O (126.08 g / mol ) = 11.2589 g H2C2O4•2H2O


Hope this answers the question. Have a nice day.

What is the total number of liters of SO3 produced when 32.0 of SO2 reacts completely
ahrayia [7]
Write  the   chemical  equation   for  reaction
that  is  
2SO2+O2  --->2SO2

find  the   moles  of  SO2   used  =  moles=mass/molar mass  of  so2

=  32g/80g/mol=0.4 moles

by  use  of  reacting  ratio  between  SO2   and  SO3   which   is   2:2  therefore  the  moles  of  so3  is  also =  0.4  moles

STP  1 mole  =  22.4L.
what  about  0.4moles

= 0.4 /1 x22.4=8.96 liters
