<span>There is only one formula to use and we should assume ideal gas. This equation is: PV=nRT. For the following questions manipulate this equation to get the answer.
1. n = PV/RT = (249*1000 Pa)(15.6 L)(1 m^3/1000 L)/(8.314 Pa-m^3/mol-K))(21+273) = 1.59 mol
2. P = nRT/V = (1.59)(8.314)(51+273)/(15.6/1000)(1000) = 274.55 kPa
3. Since the answer in #2 is more than 269 kPa, then the tires will likely burst.
4. Reduce pressure way below the limit 269 kPa.</span>
I think thats the answer but feel free to check my work
Answer:
17 mg/ml.
Explanation:
Since NaOH was titrated against Citric acid in the grape fruit, therefore
Converting g to mg,
0.1698 g * 1000 mg/1 g
= 169.8 mg
Volume of grapefruit juice = 10 ml
Mass of Citric acid in ml of juice = 169.8/10
= 17 mg/ml.
