The body mass index (BMI) estimates the armount of fat in a person's body. It is defined as the person's mass m inkilograms divided by the square of the person's height h in meters. Write the formula for BMI in terms of m and h.BMI =In the United States, most people measure weight in pounds and height in feet and inches. When weight W is measured inpounds and height h is measured in inches, the BMI formula is BMI =703W/hIdentify the product that produces the English-to-metric conversion factor of 703.A person with a BMI between 25.0 and 30.0 is considered overweight.

A pycnometer is a glass flask with a tight fitting glass stopper that can be used to determine the density of an insoluble solid by measuring the volume of water ejected out of the pycnometer when sample of the solid is placed in it. Determine the density in g/cm³ of an unknown metal alloy sample from the following measurements. Assume the density of water is 1.000 g/cm³.Mass of clean pycnometer = 25.151 gMass of clean pycnometer plus water = 42.481 gMass of clean pycnometer plus metal sample = 39.305 gMass of clean pycnometer plus metal plus water = 54.265 g (after ejected water is dried from the outside surface)
Carbon dioxide (CO2) is the gas that is mainly responsible for global warming (the greenhouse effect). The burning of fossil fuels is a major cause of the increased concentration of CO2 in the atmosphere. Carbon dioxide is also the end product of metabolism. Using glucose as an example of food, calculate the annual human production of CO2 in grams, assuming that each person consumes 5.0 × 10^2 grams of glucose per day. The world's population is 7.2 billion, and there are 365 days in a year.

A. Types of Error. A group of students is doing an analysis of copper in a 1-peso coin. They were tasked to prepare standard solutions and weigh the analyte as the end-product of their experiment. What type of error is it and explain how this type of error incurring in their experiment. Choices for Type of Error 1. Determinate error – also known as systemic error, causes the mean of a data set todiffer from the accepted value. It can cause all the results to be too high or too low. a. Instrumental error – caused by non-ideal instrument behavior, by faultycalibrations, or by use under inappropriate conditions. Calibration eliminatesmost systematic errors. b. Method error – arise from non-ideal chemical or physical behavior of analyticalsystems. It includes the slowness of some reactions, the incompleteness ofothers, instability of some species and the possible occurrence of side reactionsthat interfere with the measurement process. c. Personal error – result from carelessness,…
You record the following data during the Qualitative and Quantitative Characterization of Aspirin experiment: Mass of beaker and filter paper: 63.189 g Mass of beaker, filter paper, and solid: 63.525 g In 0.215 g of this solid, you calculated that there was 0.188 g of aspirin and 0.027 g of salicylic acid Use the percent aspirin by mass that you calculated and the total mass of solid recovered to calculate the total mass of aspirin produced (in grams).
