Answer to Question #55717 in General Chemistry for emmanuel
An undergraduate student weighed 20g of sodium carbonate salt. If Na=23, O=16, carbon = 12and H=1, what is the mole of the hydroxide?
Sodium carbonate has a formula Na2CO3.
Number of moles of sodium carbonate is:
n = m/M = 20/(23*2+12+16*3) = 0.19mol
