A mixture contains 21.7 g NaCl, 3.74 g KCl, and 9.76 g Lici. How many total moles are in this mixture?​

a force of 500                  

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

- decrease the number of plants and animals living in the water.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
