Question

stoichiometry:
determine the molar mass of...... KCl and NaNO3

Answer 1

the molar mass is the weight of 1 mole of a compound.
To find the molar mass, you just add the atomic masses of individual elements. You have those masses in the periodic table.

Answer 2

KCl: 39.10+35.45= 74.55 Is this right so far?

Answer 3

yes, that's it :)

Answer 4

so is that the answer for KCl?

Answer 5

yes that's the molar mass

Answer 6

NaNO3: 22.99+14.01+16.00+16.00+16.00=85.09

Answer 7

yup :)
