you divide the number of grams by molar mass to get the number of moles

yes and then you find the simplest whole number ratio between them.

it would help u that i had 3.1 g of NaHCO_3 and 2.2 g of NCl

hcl..u don't need the mass cuz u are finding the ratio between NaHCO_3 and NCl

for NaHCo_3 it is 83.996 and for NaCl it is 58.433

for which substances?

i fixed it...now there is :) sorry

i got 1:1 ratio.....for the equation NaHCo_3+HCl(aq) >>NaCl+Co_2+H_2_O and the simplest whole number ratio that i got for .37 and .38 is 1:1 but then that means that my percent error is o%

? The theoretical molee ratio is 1:1 and i got the experimental to be .37 mol NACl and .38 mol NaHCO_3

it is for the experimental mole ratio

really...? Okay, i did a lab on mass and mole relationships in a chemical reaction and have to fid the percent error. We used NaCl and NaHCO_3

i need help on my homework!!! Thanks, Nikki

:D

lol...he's the pimp:)

This thread will not die guys :)

hey rob....

d'accord......
