A solution of HNO3 is standardized by reaction with pure sodium
carbonate. 2H^+ + Na2CO3 ------> 2Na^+ + H2O + CO2
A volume of 28.28+-0.05 mL of HNO3 solution was required for
complete reaction with 0.8711+-0.0007g of Na2CO3 (FM
105.988+-0.001). Find the molarity of the HNO3 and its absolute
uncertainty with correct significant figures.
[HNO3] = __________M +- __________ M
Please help!!
A solution of HNO3 is standardized by reaction with pure sodium
carbonate.
2H+ + Na2CO3 -->
2Na+ + H2O + CO2
A volume of 27.87 ± 0.06 mL of HNO3 solution was required for
complete reaction with 0.8538 ± 0.0008 g of Na2CO3, (FM 105.988 ±
0.001). Find the molarity of the HNO3 and its absolute uncertainty.
Express the absolute uncertainty with three significant
figures.

If you could show me step-by-step how to do this problem, that
would be helpful.
1. How many mg of fluconazole are contained in 300 mL of a 0.4%
solution?
2. How many mL of a 20% magnesium sulfate solution will contain
14 grams of magnesium sulfate?
3.The label on a 30 mL aminophylline vial indicates a strength
of 500 mg/20 mL. How many mL of aminophylline would contain 225 mg
of the drug?
