Hi, so to solve for this, we will solve first for the number of moles of sodium carbonate.
00:10
Number of moles of na2cl3, which is going to use the measure analysis here.
00:15
If we have 0 .401, this is moles per liter, we'll multiply the volume, 475 ml, and we will convert ml to liters.
00:26
1000 ml is 1 liter, so that means we could cancel ml, then liters.
00:33
Then we have here the remaining unit moles.
00:35
This will give us 0 .190475.
00:41
This is moles of sodium carbonate.
00:45
And how do we solve for the mass? we'll just multiply the number of moles, 0 .190475, and the molar mass of na2cl3...
