(Is there any statements?)
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
Answer:
3.727x10^24 atoms.
Explanation:
When calculating how many molecules are in a compound or element, we refer to Avogardo's number.
Your equation will look like this: 1 mole/ 6.022x10^23 molecules (Avogardo's number).
Multiply 6.19 by Avogardo's number to get your answer.
