We were asked to calculate of the potassium we analyzed in a sample.
For one packet of the samople, there is 36 grams of it and from it is 240 mg of potassium.
In the lab, we weigh 0.3033g of the sample. The question is how much of potassium we have in our weighed sample based on the given data above? The answer should be in mg

Hello, we were provided two unknown samples and asked to
determine if our samples were alcohols or not, using the
2,4-di-nitrophenyl hydrazine test. Then we tested our positive
sample with Fehlings test to determine that we had a Ketone and
other sample using Lucas Reagent to determine that we had a
secondary alcohol. We were given these graphs for our unknown
samples to determine the connectivity/molecular struture. Please
kindly assist or let me know what other information would help with...

An article investigated the consumption of caffeine among women. A sample of 49 women were asked to monitor their caffeine intake over the course of one day. The mean amount of caffeine consumed in the sample of women was 242.024 mg with a standard deviation of 222.913 mg. In the article, researchers would like to include a 98% confidence interval. The values below are t critical point corresponding to 90%, 95%, 98%, and 99% confidence. Which critical point corresponds...

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 determine if the proportion for the U.S. is below.50 for an alpha level of .05. What is conclusion of my test? O I would reject Ho: P=.5 because the test statistic is...

What is the uncertainty we would predict for the velocity calculation. (assume t 2 sec) b. What is the standard deviation of our data if the following values were obtained [2.1,2.0,2.3,2.1,2.4) seconds Based on the data alone, what...

Calculating Theoretical Yield While making methyl 3-Nitrobenzoate during orgo lab we were asked to calculate theoretical yield and I not sure how to start correctly. We used 7.5ml of 18M H2SO4, and also 2.5 18M H2SO4 & 2.5mL of 16M HNO3. Then we added 2.1ml of methyl benzoate (d=1.09 g/ml) to the 7.5ml of H2SO4. Once that was all mixed, the H2SO4 & HNO3 was added to the H2SO4- menthyl benzoate mixture. Then we filtered it using suction filtration. (adding...

A sample of 120 married men between 35 and 40 years of age were asked in 1960 the source of their greatest satisfaction in life – their career, their family, or some other activity. A similar sample of 110 married men were asked the same question in 1993. Notice that the two samples -1960 and 1993 – independent (the two samples have different participants), and each person’s score can be tallied in one and only one category –career, family, or...
