Hemoglobin is a large molecule that carries oxygen in the body. An aqueous solution that contains 2.61 g of hemoglobin in 100.0 mL has an osmotic pressure of 7.52 mmHg at 25°C. What is the molar mass of the hemoglobin? Assume hemoglobin does not dissociate in water. 1.96 x 103 g/mol O 3.65 x 103 g/mol 84.8 g/mol 6.45 x 104 g/mol

Question 21 3 pts Large Sample Proportion Problem. Surveys were conducted in multiple countries and respondents were asked if they felt political news was reported fairly. The data for the United States is that out of 1,000 sampled, 470 indicated yes, they felt political news was reported fairly. Suppose we want to construct a 99% confidence interval. What is the Bound of Error (BOE)? 0.0309 2.576 0.0407 0.4293 to 5107 Question 22 3 pts Large Sample Proportion Problem. Surveys were...

Question 21 3 pts Large Sample Proportion Problem. A survey was conducted on high school marijuana use. Of the 2266 high school students surveyed, 970 admitted to smoking marijuana at least once. A study done 10 years earlier estimated that 45% of the students had tried marijuana. We want to conduct a hypothesis test to see if the true proportion of high school students who tried marijuana is now less than 45%. Use alpha = .01. What is the critical...

Question 9 4 pts Exactly 1.100 g of CO2(g) was introduced into a 1.00-L flask that already contained some O2 gas. The flask was warmed to 100 °C and the total pressure was found to be 815 mmHg. No chemical reaction occurred between CO2 and 02. Calculate the mass of Oz in the flask. 1.12 g 02 O 0.160 g 02 O 0.754 g 02 O 0.820 g 02 O 0.321 g 02 1.5 pts Question 10...
