The molar xxxxxxxxxxxxx of something xx simply xxxxxx So xxx xx xx xxxxxx is 163.94 g/mol. Using 2.0 g, you get xxx x x 163.94 g/mol = 0.0121996 mol. This is the number xx xxxxx xx xxx xxxxxxxx xxx dissolved xx 150 xx xxxxxx xxxxx for xxxxxx you xxxx xx divide xx 150 xx xxx xxxxxxxx by xxxxx xxxxxxx You will xxxx xxx xxxxxxx xxxxxx xxx xxxx it enters water, xxxxx break into Na^+ xxx (PO4)^3- xxxxx You need 3 Na^+ xxx each xxxxxxxxx xxxxx xxx multiply xxx xxxx xx 3, xxx your molar xxxxxxxxxxxxxx xxx xxxxxxx mol/L (PO4)^3- and 0.2439 xxxxx Na^+.
