divide cm3 by 1000 to get dm3 divide cm3 by 1000,000 to get m3. 2 Report. Reply. Reply 2. 18 years ago ...
I'm trying to work out the concentration: I have the mass of my solid so this is the method i used please can you confirm if it's right mass/mr= mols molx1000/volume= conc in dm3 than as you said conc x mr I need the answer to be in g cm3 not dm3?
My chemistry teacher doesn't make much sense in lessons. She said that there is a difference between dm-3 and dm3. But she didn't explain it well so i was wondering if anyone could help me out.
the formula is moles = concentration (mol/dm3) x volume (dm3) so it is mol = conc x vol mol = 0.1 x 2 mol = 0.2 hope that is right
Please help explain? The answer is C! Which reagent would exactly neutralise 100 cm3 of 1.00 mol dm–3 H2SO4(aq)? A 0.100 mol Al(OH)3 B 0.100 mol NH3 C 0.100 mol Ba(OH)2 D 0.100 mol NaOH
28 Μαρ 2016 · Therefore, there are 0.02 moles of Na2 in the Na2CO3 meaning there are 0.04 moles of Na+ in Na2CO3. 0.02 + 0.04 = 0.06 moles The total volume is 200cm3. 0.06/ 0.02dm3 = 0.3mol/dm3 Thanks! I was stupid and when I saw there was 0.02 moles NaCl, I divided it by 2 to get 0.01 moles Na+ ( ) and used the same technique for the other solution

Titration 1 Titration 2 Titration 3 Titration 4 Titration 5 Volume of 13.50 12.10 11.10 12.15 12.15 citric acid in Cm3 The equation for the reaction is: C6H8O7 + 3 NaOH C6H5O7Na3 + 3 H2O The concentration of the sodium hydroxide was 0.102 mol / dm3 Concordant results are those within 0.10 cm3 of each other.
hey, can you explain the difference between cm-3 and cm3. and dm-3 and dm3. please, this may help me to understand this question. One is the reciprocal of the other like 2 and 1/2 are the reciprocals of one another.
The dm3 just means liters so to get from literes3 to cm3 multiply by 1000
