Thank you so with those corrections my new calculations would be .0090*100.05 = .90045g Hopefully this time it is right. Obviously I am not chemisrty gifted.
chemistry
please check if I did this right ... calculate the mass of white solid CaCO3 that forms when 98ml of a 0.1M Ca(NO3)2 solution is mixed with 54 ml of a 2.5M Na2CO3 solution. Ca(NO3)2 + 2NaCO3 -> Ca(CO3)2 + 2NaNO3 .098*0.1 =.0090 .054*2.5 =.135 limiting reactant is Ca(NO3)2 ....
chemistry
lol to be honest I have no idea why it is the limiting reactant. Thank you so much for posting it helped a great deal when compared to the previous one.

mix 120ml of 0.320M silver nitrate with 40ml of 0.320M potasium chromate. What mass of silver chromate is produced? this is what i have so far 2AgNO3 + K2CrO4 --> Ag2CrO4 + 2KNO3 molar mass of 2agno3 = 277.81 molar mass of k2cro4 = 194.2 molar mass of ag2cro4 = 331.8 limiti...

Thank you so much, now I understand ... I think :)
Chemistry
this is what I came up with 2AgNO3+k2CrO4--->Ag2CrO4+2KNO3 molar mass of 2agno3 = 277.18 molar mass of k2cro4 = 194.2 molar mass of ag2cro4 = 331.08 194.2*277.18/120ml=500ml limiting reactant k2cro4 194.2g*331.08g/500=128.60 128.60*331.08/1000=42.6 is this anywhere near right?

mix 120ml of 0.320M silver nitrate with 40ml of 0.320M potasium chromate. What mass of silver chromate is produced? I am stuck please help
chemistry
I have 3 questions I need help with 1. mix 120ml of 0.320M silver nitrate with 40ml of 0.320M potasium chromate. What mass of silver chromate is produced? 2. Calculate the mass of white solid CaCO3 that forms when 98ml of a 0.1M Ca(NO3)2 solution is mixed with 54ml of a 2.5M N...
