dm3 m3 and cm3. GJS. 1. whats the link between them all e.g. in gas eqiutions your meant to use m3, how do ...
In fact, in the ideal gas equation you can use dm 3 PROVIDING that you use kPa for the pressure units. It's either volume in dm 3 and pressure in kPa or volume in m 3 and pressure in Pa In solutions you should always work in dm 3 of solution and moles of solute.
I've got my practical chemistry test soon and I need to know this. 1. How do I convert moldm3 to gdm3 and the reverse conversion, using what numbers I'm likely to have.
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?
The dm3 just means liters so to get from literes3 to cm3 multiply by 1000. 0 Report. Reply 3. 18 years ago ...
Everyday worries about starting university (and what to do about them) What is student accommodation like at uni?
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.
12 Μαΐ 2023 · I need help with an question I don’t understand why then converted the volume to m3 when it was already in dm3 A gas cylinder has a gas volume of 9.39 dm3 The gas cylinder holds 1.69kg of a gas at a pressure of 1.37 x 10^7 Pa at 20•c Determine the molar mass and possible identity of the gas Can some one explain how to do this question I know what to do I just don’t get why they converted ...
7 Μαΐ 2021 · Calculate the mass of dissolved solid in 1 m3 of this water sample. 1 m3 = 1000 dm3 0.016 grams in 25cm3 So how many grams in 1cm3? And once you find this, multiply this by 1000000 to find the mass present in 1 m3.
so firstly, i used the formula n=PV/RT convert all units to correct ones, so dm3>m3 is /1000 400/1000 = 0.4 using the formula-0.4*(1*10^5)/301*8.31 (it said ideal gas condition) = X since the initial stated it required 2 moles of the alkane to produce this c02, therefore, /2 to calculate the singular molar for it, which results in 8 carbons (7.99) from the options available, it would be c8h18 ...
