Answer:
O B. Convert the 10 g of NaCl to moles of NaCl.
Explanation:
The formula for finding the molality is m=moles of solute/kg of solvent. The solute for this question is NaCl and the solvent is water.
(10g NaCl)(1 mol NaCl/58.44g NaCl)=0.1711 mol NaCl
58.44 is the molar mass of NaCl
m=0.1711 mol NaCl/2 kg H2O
m=0.085557837
NH₄Cl → NH₄⁺ + Cl⁻
NH₄⁺ (the ammonium cation)
I believe it is answer 2 and 4
Answer:
particles have mass unique to their substance
Explanation:
for example using cereal ->
1 Frosted mini wheat is much larger than 1 cheerio so it has a higher mass -> They are both single particles but without knowledge of their unique mass we can't convert particle number to grams!
hope this helps !! :)
