The reverse line in N 66°48'E. However. surveys almost always use true north, not magnetic north as a compass indicates. You need to correct for your... -
Use 312.5 g of it and dilute in water to make 1 L final volume, as listed previously. 312.5 g x 80% = 250 g. Mixed to 1 L of mixture thats 250 g/L or...Leave a comment:

Do you know what you want? In post #29, I'm not sure if you want 1 L or all you can make from 400 g of impure powder. In post #21 you seem to have changed...Leave a comment:

We have previously discussed how concentrations in percent are confusing and meaningless unless the basis is stated mass/mass, volume/volume, mass/volume,...Leave a comment:

I'm not sure what you mean by the first part of your concentration, assuming it is 35.4% HCl
35.4 x V1 = 4 x 100 mL, then V1 = 11 .43 mL.

I assume you mean mass/volume percent as before so 250 g/L of NaClO2. You only want 100 mL, so you need 25 g NaClO2. However, it is only 80% pure, so...Leave a comment:

Best case: Severe Frost bite
Worst Case: Your hands freeze solid, and either shatter or fall off.
Strongly not recommended....Leave a comment:

The M is shorthand for moles per liter, mol/L. The only way to convert between molar and mass concentrations is to know the molecular weight. Do you know...Leave a comment:
